term "myotome" is also used to describe the muscles served by a single nerve root. It is the motor equivalent of a dermatome. Each muscle in the body is supplied by a one or more levels or segments of the spinal cord and by their corresponding spinal nerves.Myotomes & Dermatomes dermatome map - Apparelyzed www.apparelyzed.com/myo-dermatomes.html Myotomes and dermatome charts & maps describe the relationship between spinal nerve ... Dermatome is a Greek word which literally means "skin cutting".

The metabolic process providing my energy while I was walking at an easy pace is aerobic metabolism. During aerobic metabolism‚ mitochondria absorb from the surrounding cytoplasm these molecules: ADP‚ phosphate ions‚ O2‚ and organic substances like pyruvate. These molecules go through the citric acid cycle. The electron

Optic Nerve The optic nerve is located in the back of the eye and is also called second cranial nerve and cranial nerve II. the optic nerve is to transfer visual information from the retina to teh vision centres of the brain via electrical impulses. It is made up of ganglionic cells or nerve cells and consists of more than 1 million nerve fibres . Our blind spot is caused by the absence of specialised photosensitive/light-sensitive cells or photoreceptors; the part of the retina where the optic

main factor that leads to the damage of optic nerve is elevated pressure in the eye. The optic nerve is the main visual nerve of the eye. It transmits the images we see back to the brain for interpretation. The shape and tone of the eye is maintained by a pressure within the eye‚ which ranges between 8 mm and 22 mm of mercury. When this pressure is too low‚ the eye becomes softer‚ while an elevated pressure causes the eye to become harder. The optic nerve is the most susceptible part of the eye to high

Nerve and neuron sound similar to most people‚ but they are two different components of the body (Martini‚ 375). Nerves are found only in the peripheral nervous system‚ while neurons are found in the brain‚ spinal cord‚ and peripheral nerve (Martini‚ 375). Neurons are nerves cells that are specialized for intercellular communication (Martini‚ 375). A neuron is composed of a cell body‚ dendrites and axon (Marieb‚ 376). A nerve is a bundle of axons or dendrites that is wrapped in connective tissues

well as adds curvature to the spine. Occasionally tumors develop on the brain or spinal cord. Half of the people with NF1 also inhibit learning disabilities. The less common disorder‚ NF2‚ characterizes itself by multiple tumors on cranial and spinal nerves. Hearing loss will nearly inevitably occur in the early teens for people with NF2.

identify neurologic changes by performing a bedside assessment. A proper bedside assessment includes: vital signs‚ pupillary responses‚ posturing response‚ hand grasp‚ muscle strength and symmetry‚ sensory evaluation‚ and an evaluation of the cranial nerves (Crimlisk & Grande‚ 2004). A registered nurse may also be asked to help a physician perform neurologic tests. These include superficial cutaneous reflexes‚ deep tendon reflexes‚ and vestibular reflexes (Crimlisk & Grande‚ 2004). Superficial
