1.
autonomic nervous system: the part of the nervous system of vertebrates that controls involuntary actions of the smooth muscles and heart and glands
2.
axillary nerve: innervates the deltoid, teres minor, and skin and joint capsule of the shoulder
3.
cerebral angiogram: x-ray of blood vessels in the brain after intracarotid injection of contrast medium
4.
collateral ganglion: splanchnic nerves which travel to the viscera to synapse with a ganglionic neuron
5.
common fibular nerve: innervates muscles of the anterolateral leg
6.
CT scan: a series of x-ray photographs taken from different angles and combined by computer into a composite representation of a slice through the body.
7.
EEG: eletroencephalogram; an amplified recording of the waves of electrical activity that sweep across the brain's surface. These waves are measured by electrodes placed on the scalp
8.
femoral nerve: innervates quadriceps and skin of anterior thigh and medial surface of leg
9.
gluteal nerve: controls extensors of hip
10.
involuntary nervous system: Another name for Autonomic Nervous System
11.
median nerve: innervates the skin, most flexors and pronators in the forearm, and some intrinsic muscles of the hand
12.
MRI scan: uses magnetic fields and radio waves to produce computer-generated images that distinguish among different types of soft tissue
13.
musculocutaneous nerve: innervates the biceps brachii and brachialis and skin of lateral forearm
14.
obturator nerve: controls adductors of hips
15.
parasympathetic division: a branch of the autonomic nervous system that maintains normal body functions; it calms the body ever conserves energy
16.
PET scan: a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task
17.
phrenic nerve: one of a pair of nerves that arises from cervical spinal roots and passes down the thorax to innervate the diaphragm and control breathing
18.
pneumoencephalography: radiographic films of the brain utilizing injections of air or gas
19.
postganglion axon: 2nd neuron outside on the CNS that extends to the organ it serves
20.
preganglionic axon: one of a chain of motor neurons; leaves the CNS to synapse with 2nd motor neron in a ganlion outside the CNS
21.
radial nerve: innervates essentially all extensor muscles, supinators, and posterior skin of limb
22.
ramus communicans: Branch of spinal nerve; connects to sympathetic trunk and innervates viscera
23.
sciatic nerve: arises from the sacral plexus and passes about halfway down the thigh where it divides into the common peroneal and tibial nerves
24.
splanchnic nerves: nerves carrying impulses from the thoracic and lumbar parts of the spinal cord to the digestive organs and from the digestive organs to the spinal cord; they convey information about the nutrient content of food in the digestive system
25.
sympathetic chain ganglion: What ganglion receives preganglionic sympathetic fibers from T1 to L1-2 and innervates smooth muscle, cardiac muscle, glands, head, thoracic viscera, and blood vessels of the body wall and limbs?
26.
sympathetic division: The branch of the autonomic nervous system that mobilizes the body's resources for emergencies.
27.
sympathetic trunk: This nerve runs along each side of the vertebral column. It receives neurons from anterior rami of the spinal nerves via the sympathetic trunk ganglia. It serves many organs from the head to the pelvis. Because it receives nerves from the intervertebral foramina it is difficult to lift away from the body wall. In the neck it runs with the vagus nerve (X).
28.
terminal ganglion: a cluster of cell bodies of parasympathetic postganglionic neurons either lying very close to the visceral effectors or located within the walls of the visceral effectors supplied by the postganglionic neurons
29.
tibial nerve: a branch of the sciatic nerve that passes through the popliteal fossa to pass below the arch of soleus.
30.
ulnar nerve: supplies the flexor carpi ulnaris, part of the flexor digitorum profundus, most intrinsic muscles of the hand, and skin of medial aspect of hand
