Our body is composed of complicated and intricate systems that work together to keep us alive and able to move and process the things we find to be simple such as breathing or blinking. There are 11 systems in our body‚ each in charge of something different and supplying support to the other. Those 11 systems are the‚ nervous‚ skeletal‚ muscular‚ circulatory‚ respiratory‚ digestive‚ endocrine‚ reproductive‚ excretory‚ integumentary and immune systems. I will address every system in the human body

Parkinson’s disease and Huntington’s disease are associated with defects of the basal ganglia. What is the function of the CSF? (pg 461) CSF is a clear‚ colorless fluid similar to blood plasma and interstitial fluid. The intracranial and spinal cord structures float in CSF and are thereby protected from jolts and blows. CSF also prevents the brain from tugging on meninges‚ nerve roots‚ and blood vessels. Where is CSF produced? (pg. 461) The choroid plexuses in the lateral‚ third‚ and

Preganglionic Neuron – First neuron that resides in the brain or spinal cord. 3. Preganglionic Axon – Synapses with the second motor neuron; thin‚ lightly myelinated. 4. Postganglionic Neuron – Second motor neuron. 5. Autonomic Ganglion – Cell body of the postganglionic neuron is located here outside the CNS

Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease that affects the brain and spinal cord. Coming from Greek language Amyotrophic simply means no muscle nourishment (alsa.org). Lateral is the anatomical identification along the spinal cord and as the disease progresses‚ it eventually leads to sclerosis which is hardening of the region along the spinal cord. ALS was first discovered in 1869 by a famous French neurologist named Jean- Martin Charcot‚ ALS was originally named

discomfort in the affected area‚ and results in a smaller scar. Spinal fusion is the most common type of surgery for back patients. In a spinal fusion a surgeon joins spinal bones together‚ restricting motion between the bones of the spine. Fusion also limits the stretching of nerves. Another example is a laminectomy in which a surgeon removes parts of the bones or ligaments in the back (Liebenson). This surgery helps relieve pressure on spinal nerves that may be causing pain or weakness. During a foraminotomy

Definition Reflex tests are simple physical tests of nervous system function. Purpose A reflex is a simple nerve circuit. A stimulus‚ such as a light tap with a rubber hammer‚ causes sensory neurons (nerve cells) to send signals to the spinal cord. There‚ the signals are conveyed both to the brainand to nerves that control muscles affected by the stimulus. Without any brain intervention‚ these muscles may respond to an appropriate stimulus by contracting. Reflex tests measure the presence and
