GRADED A PLUS
◉ peripheral nervous system
Answer: consists of nerves and ganglia, all nervous tissue structures
outside to the CNS
◉ Afferent division of PNS
Answer: SENSORY impulses are carried from sensory receptors
through the PNS toward the CNS
◉ Efferent division
Answer: MOTOR impulses carried away from the CNS, through the
PNS to the effectors which are muscles and glands
◉ Efferent division is further subdivided into
Answer: Somatic nervous system
Automatic nervous system
◉ somatic nervous system
, Answer: provides voluntary control over skeletal muscle contraction
◉ Automatic nervous system
Answer: provides automatic control, so regulation of smooth muscle,
cardiac muscle and glandular activity
◉ Nureons
Answer: responsible for the transfer and processing of information
in the nervous system
◉ Neuroglia
Answer: supporting cells
◉ Astrocytes (CNS)
Answer: maintain blood- brain barrier
repair damaged neural tissue
