Exam 1: Divisions of the Nervous System + More Flashcards
Central Nervous System
-Made up of the brain & spinal cord
Peripheral Nervous System
A portion of the nervous system that includes all the nerves and neurons outside the brain and spinal cord.
Somatic
A part of the peripheral nervous system that supplies neural connections mostly to the skeletal muscles and sensory systems of the body. It consists of cranial nerves and spinal nerves.
Autonomic
A part of the peripheral nervous system that provides the main neural connections to the internal organs.
Sagittal Plane
The plane that divides the body or brain into right and left portions.
Sympathetic
The part of the autonomic nervous system that acts as the fight-or-flight system, generally preparing the body for action.
Afferent
Carrying action potentials toward the brain, or one region of interest from another region of interest.
Parasympathetic
The part of the autonomic nervous system that generally prepare the body to relax and recuperate
Efferent
Carrying action potentials away from the brain, or away from one region of interest toward another region of interest.
Coronal Plane
Also called the frontal plane or transverse plane. The plane that divides the body or brain into front and back parts.
Horizontal Plane
The plane that divides the body or brain into upper and lower parts.
Dorsal/Ventral
D: In anatomy, toward the back of the body or the top of the brain.
V: In anatomy, toward the belly or front of the body, or the bottom of the brain.
Rostral/Caudal
R: Also called anterior. In anatomy, toward the head end of an organism.
C: Also called posterior. In anatomy, toward the tail end of an organism.
Superior/Inferior
S: In anatomy, above.
I: In anatomy, below
Medial/Lateral
M: In anatomy, towards the middle.
L: In anatomy, towards one side.
