The deltoid is a large, thick powerful muscle with a triangular form and a coarse texture. The muscle is divided into three portions: an anterior (clavicular) portion, and acrominal portion, and a posterior portion. The anterior portion forms the broad side of the muscle and the posterior portion is located on the back of the shoulder. The muscle originates from the clavicle and from the spine of the scapula covering the outer side of the shoulder joint, giving the shoulder its rounded appearance, and inserts in the humerus. The deltoid is innervated by the 5th and 6th cervical nerves through the circumflex nerve and supplied by the circumflex artery. Almost any movement of the shoulder and upper arm involves the deltoid muscle. The anterior portion is used to raise the arm from the body and to lower it again. The acrominal portion is a powerful abductor and the posterior portion is used to move the arm backward. It works with the pectoralis major to move the arm forward and works with the teres major and latissimus dorsi to move the
arm back.

Dentine (dentin) is the main substance of the tooth, composing the bulk of the crown and root of the tooth.
Dentine is similar in hardness to compact bone tissue, found throughout the skeleton, and features about 30% organic tissue. Like the enamel, no cells or vessels penetrate the
dentine, so that damage to the dentine (as in the case of a dental cavity) cannot be repaired. In some teeth, a secondary dentine may form as an accretive patch over damaged or occluded tooth tissue, however. Though no cells or vessels penetrate the dentine, small tubules do penetrate into the dentine matrix from the pulp cavity. Within these tubules are housed odontoblasts in a protoplasmic base. These tubules make the dentinal matrix sensitive to contact or temperature changes.

The dermal papillae are small, nipple-like protrusions of the dermis that reach into the epidermis, bringing food and oxygen to the lower layers of epidermal cells. In addition, a papilla nourishes every hair follicle. Rows of papillae protruding from the dermis into the epidermis form ridges that create patterns on the skin of the hands, feet, and body. These papillary ridges on the fingertips are responsible for fingerprints. These ridges develop sometime before birth. Not only is the pattern unique for each individual, but also it never changes except to grow larger.

The diaphragm is the primary muscle responsible for respiration. Connected to the abdominal wall, the lumbar vertebra, the lower ribs, the sternum, and the pericardium of the heart by tendinous tissue, the thin diaphragm creates a partition between the thoracic and abdominal cavity. The
diaphragm forms a domed structure, and when the diaphragm muscle contracts, it lowers to a more flattened arrangement. This flattening causes a vacuum in the thoracic cavity and pressure in the abdominal cavity. The vacuum is filled by the expanding lung tissue and inhaled air. The pressure on the lower viscera are helpful in childbirth and in pushing fecal matter through the lower intestinal tract for expulsion. When the diaphragm relaxes to its domed structure, the air is exhaled and the lungs contract. Though the intercostal and abdominal muscles are also used in respiration, during sleep, it is primarily due to contractions of the diaphragm. The diaphragm is supplied by the inferior and superior phrenic arteries and the musculophrenic artery. It is innervated phrenic nerve.

The digestive system is responsible for processing food, breaking it down into usable proteins, carbohydrates, minerals, fats, and other substances, and introducing these into the bloodstream so that they can be used by the body. The digestive, or alimentary, tract begins at the mouth, where the teeth and tongue begin the breakdown of food, aided by saliva secreted by the salivary glands. The chewed food, combined with saliva, is swallowed, carrying it in peristaltic waves down the esophagus to the stomach. In the stomach, the food combines with hydrochloric acid which further assists in breaking it down. When the food is thoroughly digested, the fluid remaining, called chyme, is passed through the pylorus sphincter to the small intestine and large intestines. Within the long, convoluted intestinal canals, the nutrients are absorbed from the chyme into the bloodstream, leaving the unusable residue. This residue passes through the colon (where most of the water is absorbed into the bloodstream) and into the rectum where it is stored
prior to excretion. This solid waste, called faeces, is compacted together and, upon excretion, passes through the anal canal and the anus. Along the way through the digestive tract, the pancreas, spleen, liver, and gall bladder secrete enzymes which aid in the digestive process.

Diphtheria is an acute, contagious disease produced by the Klebs-Loeffler bacillus. Diphtheria is unusual in that after infection it does not spread in the body, but the bacillus remains at the site of its primary invasion. This site may be the fauces in front of the throat, or the larynx. Very occasionally the bacillus gains access to a wound and gives rise to 'wound diphtheria'. In any case, the disease multiplies and produces a membrane which in the case of the laryngeal type may produce death by mechanical blockage of the air passage. The chief danger however lies in the toxins discharged by the bacillus which enter the blood system and affect the muscles in particular, giving rise to a danger of heart-attacks.

Duchenne muscular dystrophy is the most common form of muscular dystrophy, and is transmitted by an X-linked recessive trait. Only males are affected and only females are carriers that pass the trait on. The disorder cannot be detected by amniocentesis. It affects about 1 in 10,000 boys. Symptoms of the disorder begin to appear in early childhood between the ages of two to six years. The pelvic and leg muscles are affected first. The child is slow in learning to sit up and walk. Progressive and rapid weakening of the muscles results in frequent falls, difficulty in climbing stairs, difficulty in getting up from the floor, and an awkward gait. Sometimes a curvature of the spine is associated with the disorder. Despite their weakness, the muscles appear unusually large and firm (psuedohypertrophy). At about early adolescence affected children are no longer able to walk. Children with Duchenne's muscular dystrophy are prone to chest infections and heart disorders due to progressive weakening of those muscles. Few sufferers survive into their teenage
years.

Dysentery is of two main types, namely bacillary and amebic, caused by different forms of infection, but in both there is inflammation of the mucous membrane lining the lower or large bowel. The symptoms are those of enteritis and colitis, diarrhaea with small loose stools containing mucus and blood, abdominal tenderness, griping pain, and tenesmus during evacuation. Bacillary dysentery is a very infectious disease caused by various specific bacterial organisms (Sonne, Shiga and Flexner bacilli) which occur in impure water, contaminated food and excreta, and are often conveyed by flies or by 'carriers'. The incubation period may be only a few hours, and is seldom more than three days. The disease is prevalent where insanitary conditions occur, and epidemics are common especially in the tropics. The disease develops suddenly with loss of appetite, lassitude, fever, shivering, heat of the skin, and a quick pulse. These are followed by griping pains in the bowels, and a constant desire to evacuate, and prostration. In general the stools are
small and slimy, composed of mucus mixed with blood. Defaecation is attended and followed by severe griping and inclination to strain, called tormina and tenesmus; they are sometimes in the early stages attended by nausea and vomiting. The natural faeces are passed in the first few evacuations. Tenesmus continues and perhaps increases for several days, the discharges being mostly blood in some cases, and chiefly mucus in others. Having generally but little odour at first, these discharges become, as the disease advances, exceedingly offensive. Vomiting is common, and there may be a high or low temperature, with headache. The disease may be severe or moderate in its course. In severe cases there are thirst, muscular pains, blueness of the face, extreme tenderness of the abdomen, hiccough, prostration, incontinence and a high mortality rate. If recovery follows convalescence is slow, with recurrent diarrhaea and various complications such as arthritis, iritis, chronic colitis, peritonitis, piles, boils, etc. In mild cases the symptoms abate after four or
five days.

Dyspraxia (also known as Clumsy Child Syndrome, Developmental Coordination Disorder (DCD), Perceptuo-motor Dysfunction, Minimal Brain Dysfunction and Motor Learning Difficulty) is a believed (but unproven) immaturity of the brain though to result in messages not being properly transmitted to the body. It is believed by advocates of the theory to affect at least 2% of the British population in varying degrees of severity with 70% of those affected being male. Symptoms of dyspraxia may include some of: clumsiness; poor posture; awkward walking; confusion over which hand to use; difficulties in throwing or catching a ball; sensitivity to touch; finding some clothes uncomfortable; poor short term memory; poor body awareness; difficulties with reading and writing; inability to hold a pen or pencil properly; poor sense of direction; lack of balance; slow development; inability to answer simple questions even though they know the answer; speech problems, slow to learn to speak or incoherent speech; phobias and obsessive behaviour;
impatience; intolerance to having hair or teeth brushed, nails and hair cut; plasters too uncomfortable to wear. Though advocates of dyspraxia claim that different sufferers will suffer various symptoms, not all suffering all or even the same symptoms. Older sufferers typically display signs of very immature behaviour. Recent discoveries have found that often sufferers of dyspraxia hallucinate taste sensations when speaking, that is pronouncing different words gives rise to different tastes in the mouth. The Bronte sisters were thought to suffer from dyspraxia, and often sufferers excell in language and literature, while facing severe difficulties with inter-personal relationships and motor coordination.
