These important ions help regulate homeostasis in our bodies‚ as well as allowing us to move‚ absorb food‚ heal‚ and reproduce. Understanding how these ions work within our bodies will allow us to comprehend the physiology behind muscle contraction‚ nerve signaling and cell signaling.

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 connected to the cervical plexus. The figure 13.4 in the book lists the innervation of the ulnar nerve is the skin of palmer and medial hand and digits III-V:

all of the nerves that connect these organs with the rest of the body. Together‚ these organs are responsible for the control of the body and communication among its parts. The brain and spinal cord form the control center known as the central nervous system (CNS)‚ where information is evaluated and decisions made. The sensory nerves and sense organs of the peripheral nervous system (PNS) monitor conditions inside and outside of the body and send this information to the CNS. Efferent nerves in the PNS

malfunctions of the nerves. Disorders can range from Palsy and Parkinson’s in which symptoms are movements such as tremors to Alzheimer’s which is mental deterioration and loss of memory. Disorders stemming from the nervous system can be severe. A few disorders that deal with movement and muscles are Amyotrophic lateral sclerosis (also known as Lou Gehrig’s disease)‚ Myasthenia gravis‚ and as said before Parkinson’s. Amyotrophic lateral sclerosis is a disease of the nerve cells in the brain and
