Central Nervous System
MAJOR FUNCTIONS
-
INTEGRATIVE FUNCTION: It analyzes sensory information, stores some aspects, and makes decisions regarding appropriate behaviors
Motor Functions: It may respond to stimuli by initiating muscular contractions or glandular secretions
-
LOBES
-
Parietal: Processing sensory information regarding the location of parts of the body and interpreting visual information
-
Frontal: Problem solving, memory language, impulse control
LAYERS OF MENINGES
-
DURA MATER
Dense, irregular, CT with many blood vessels and nerves
-
PIA MATER
-
-
Innermost, nearly transparent layer; has many nerves and blood vessels
SPINAL CORD
-
WHITE MATTER
-
-
Anterior, posterior, and lateral white columns
-
FUNCTION
Gray matter receives and integrates information, especially for spinal reflexes
-
-
GRAY MATTER
-
Lateral Horn: Located on the side cell bodies of motor neurons tp cardiac, and smooth muscle and galnds
-
-
-
ACTION POTENTIAL
If a strong depolarization occurs, threshold potential is reached and impulse is sent down axon
-
K+ rushes out of neuron after Na+ rush in, which causes a re-polarization of the membrane back to resting potential
