Dermatome Anatomy Essay Sample

Dermatome Anatomy Essay Sample A dermatome is an area of skin that is mainly supplied by a single spinal nerve. There are eight cervical nerves (C1 being an exception with no dermatome), twelve thoracic nerves, five lumbar nerves and five sacral nerves. Each of these nerves relays sensation (including pain) from a particular region of skin to the brain. Along the thorax and abdomen the dermatomes are like a stack of discs forming a human, each supplied by a different spinal nerve. Along the arms and the legs, the pattern is different: the dermatomes run longitudinally along the limbs. Although the general pattern is similar in all people, the precise areas of innervation are as unique to an individual as fingerprints. A similar area innervated by peripheral nerves

The Importance of Understand Human Anatomy Essay Sample

The Importance of Understand Human Anatomy Essay Sample Is it important to understand human anatomy? The answer to this question goes back to the beginning of human race. The basic knowledge about human anatomy was acquired thousands, if not a million, years ago. The first humans could use this knowledge for such basic purposes as to know how and where to hit their enemies (also humans). The stone thrown into the forehead did not kill; however, the person hit in the temple could die instantly. The arrow piercing the heart did the same job. The first humans learned the anatomical location of body organs by everyday experience. Later shamans and patriarchs, who carried it through the centuries, adding new discoveries to this knowledge, preserved this knowledge. With

Anatomy: Polydactyly Essay Sample

Anatomy: Polydactyly Essay Sample Polydactyly is a condition in which the patient has more than five fingers on his hands or more than five toes on his feet. This anatomical abnormality is a congenital abnormality. Patients will have six or more toes or fingers at birth. It is estimated that every two in one thousand children will be born with this disorder. Certain populations have a higher incidence rate due to the founder effect, such as the Pennsylvania Dutch in the USA. The one question many patients, and parents, ask is “how is polydactyly inherited? CausesDuring normal embryonic development (while the baby is still in the womb), the hand initially forms in the shape of a paddle, and then—at about the sixth or seventh week of gestation—splits into separate

A Review of Facial Nerve Anatomy Essay Sample

A Review of Facial Nerve Anatomy Essay Sample An intimate knowledge of facial nerve anatomy is critical to avoid its inadvertent injury during rhytidectomy, parotidectomy, maxillofacial fracture reduction, and almost any surgery of the head and neck. Injury to the frontal and marginal mandibular branches of the facial nerve in particular can lead to obvious clinical deficits, and areas where these nerves are particularly susceptible to injury have been designated danger zones by previous authors. Assessment of facial nerve function is not limited to its extratemporal anatomy, however, as many clinical deficits originate within its intratemporal and intracranial components. Similarly, the facial nerve cannot be considered an exclusively motor nerve given its contribut

Physiology And Anatomy Essay Sample

Physiology And Anatomy Essay Sample Part one:If you step up one step using your right leg, the impulse will arise from the motor cortex in the left cerebral hemisphere of your brain. The impulse then travels through the corticobulbar tract through the midbrain, then the pons and medulla until it exits the skull through the occipital foramen and enters your spinal cord. In the spinal cord, the impulse travels down until the tract decussates to the right side of the cord and synapse with the right lateral corticospinal tract. From the spinal cord the impulse travels through specific nerves that branch outside the spinal column to specific muscle groups depending on the movement. The action of stepping up one step involves two motions: first, the flexion of your hip

Anatomy And Physiology Of The Digestive System Essay Sample

Anatomy And Physiology Of The Digestive System Essay Sample The digestive system is basically a tube running through the body from the mouth to the anus. The organs of the digestive system include the oral cavity (mouth), esophagus, stomach, small and large intestine and rectum. Their role is to break down food and deliver the products to the blood for dispersal to the body cells. The undigested food that remains in the tract leaves the body through the anus as feces. The break down activities that begin in the mouth are completed in the small intestine. From that point on, the major function of the digestive system is to reclaim water. The liver is considered to be a digestive organ, because the bile it produces helps to break down fats. The pancreas which deliver
