Gross Skeletal Muscle
What is Supinator?
What is the peripheral NS?
This layer of the surrounds the entire spinal nerve and is composed of dense irregular CT.
What is the epineurium?
This structure is the largest part of the CNS.
What is the cerebrum?
This muscle flexes the trunk.
What is the rectus abdominis?
The subscapularis is the medial rotator for this muscle group.
What is the rotator cuff muscle group?
This synapse occurs between a neuron and motor unit.
What is a neuromuscular junction?
This nerve innervates muscles and skin of the hand.
What is the ulnar nerve?
This brain structure is responsible for simple movements, like flexion.
What is the precentral gyrus?
These are the group of spinal nerves inferior to the caudal end of the spinal cord.
What is the cauda equina?
The gluteal muscles move the hip in these two motions.
What is abduction and extension?
These CT layers protect and provide nutrients to the spinal cord and brain.
What are the meninges? (dura, arachnoid, pia)
The loss of sensation and muscle control are characterized by this.
What is a spinal nerve lesion?
This white matter structure connects neuron cell bodies in 1 hemisphere only.
What are the association fibers?
The obturator nerve innervates this region.
What are the muscles and skin of the medial thigh?
The trapezius is an antagonist to the serratus anterior, and completes these 3 motions for the shoulder.
What is elevation, depression, retraction?
This is the only glial cell that functions in the Peripheral NS.
What are Schwann cells?
Herpes zoster virus and a herniated disks are caused to this kind of lesion.

This speech center is located in the frontal lobe and is responsible for what language function.
What is the Broca's area for speaking?
Degeneration of the myelin sheath is the cause of this disorder.
What is multiple sclerosis?
This category of muscles cross two joints.
What are biarticular muscles?
This structure receives and sums signals from brain motor neurons.
What is the ventral horn of the spinal cord? (gray matter motor neuron cell bodies)
Sciatica is caused by inflammation of the piriformis that puts pressure on this nerve.
What is the sciatic nerve?
Degeneration of this brain structure is associated with Parkinson's disease.
What is the basal ganglia?
Atrophy of white matter in the brain is associated with this disorder.
What is Alzheimer's disease?
