-
Central Nervous System
brain and spinal cord
-
Peripheral Nervous System (consists and contains)
consists of the nerves outside the brain and spinal cord. Contains somatic, automic, sympathetic and parasympathetic.
-
Somatic Nervous System
Control voluntary muscles and conveys sensory information to the central nervous system
-
Autonomic
controls involuntary muscles
-
Sympathetic
expends energy
-
parasympathetic
conserves energy
-
Dorsal
toward the back, away from the ventral (stomach) side.
-
Ventral
toward the stomach, away from the dorsal (back) side
-
Anterior
toward the front end
-
Posterior
Toward the rear end
-
superior
above another part
-
inferior
below another part
-
lateral
toward the side, away from the midline
-
medial
toward the midline, away from the side
-
proximal
located close to the point of origin or attachment
-
distal
located more distant from the point of origin or attachment
-
ipsilateral
on the same side of the body (two parts on the left or two on the right)
-
contralateral
on the opposite side of the body (one on the left and one on the right)
-
Coronal plane
a plane that shows brain structure as seen from the front
-
sagittal plane
a plane that shows brain structures as seen form the side
-
horizontal plane
a plane that shows brain structures as seen from above
-
spinal cord
part of the CNS within the spinal column. commumicates wit hall the sense organs and muscles except those of the head. segmented structure
-
Bell-Magendie Law
one of the first discoveries about the functions of the nervous system, the entering dorsal roots (axon bundles) carry sensory information, and the exiting ventral roots carry motor information. The axons to and from the skin and muscles are the PNS.
-
dorsal root ganglia
clusters of neurons outside the spinal cord.
