autonomic nervous system
the part of the nervous system of vertebrates that controls involuntary actions of the smooth muscles and heart and glands
one of a pair of nerves that arises from cervical spinal roots and passes down the thorax to innervate the diaphragm and control breathing
innervates the skin, most flexors and pronators in the forearm, and some intrinsic muscles of the hand
supplies the flexor carpi ulnaris, part of the flexor digitorum profundus, most intrinsic muscles of the hand, and skin of medial aspect of hand
arises from the sacral plexus and passes about halfway down the thigh where it divides into the common peroneal and tibial nerves
a branch of the sciatic nerve that passes through the popliteal fossa to pass below the arch of soleus.
The branch of the autonomic nervous system that mobilizes the body's resources for emergencies.
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
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?
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).
splanchnic nerves which travel to the viscera to synapse with a ganglionic neuron
a branch of the autonomic nervous system that maintains normal body functions; it calms the body ever conserves energy
one of a chain of motor neurons; leaves the CNS to synapse with 2nd motor neron in a ganlion outside the CNS
a series of x-ray photographs taken from different angles and combined by computer into a composite representation of a slice through the body.
uses magnetic fields and radio waves to produce computer-generated images that distinguish among different types of soft tissue
a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task
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
x-ray of blood vessels in the brain after intracarotid injection of contrast medium
