Reflexes Laboratory Activity (12 points) 1. Amy has numbness of her pinky‚ ring finger‚ and medial surface of her right arm. After neurological testing‚ it is determined that she has a compressed spinal nerve on the right side. a. Which spinal nerve (what level) is affected? The level is C5-T1 cervical nerves. The specific spinal nerve would belong to the brachial plexus‚ the ulnar nerve. b. How did you determine/decide it was this level? The ulnar nerve branches off of the medial cord‚ which is

The Physiology and Pathophysiology of the Skin Abstract The 5-HT3 receptor is a ligand-gated cation channel located in the central and peripheral nervous system; it has also been detected on a variety of other cells. In the periphery‚ it is found on autonomic neurons and on neurons of the sensory and enteric nervous system. In the CNS‚ the 5-HT3 receptor has been localized in the area postrema‚ nucleus tractus solitarii‚ nucleus vaudatus‚ nucleus accumbens‚ amygdala‚ hippocampus‚ entorhinal‚

The brain and spinal cord are made up of many cells‚ including neurons and glial cells. Neurons are cells that send and receive electro-chemical signals to and from the brain and nervous system. There are about 100 billion neurons in the brain. There are many more glial cells; they provide support functions for the neurons‚ and are far more numerous than neurons. There are many type of neurons. They vary in size from 4 microns (.004 mm) to 100 microns (.1 mm) in diameter. Their length varies from

In this case the man suffers from a sympathetic preganglionic lesion‚ and the neurotransmitter needed in order to communicate with the postganglionic neuron is Ach. (12) To create an excitatory response in the cholinergic-nicotinic receptor without having the neuron release the neurotransmitter‚ doctors can administer a nicotinic agonist in order to make the transmission of the signal possible. The nicotinic drug will mimic the action of Ach. (5‚13) Unfortunately‚ recreating Ach action could create
