APK2100C Chapter 12 Test With
Complete Solution
The Nervous System [Overview] - ANSWER - Master controlling and
communication system of the body
- Responsible for actions like muscle contractions or reflexes
Describe the signals produced by the nervous system. - ANSWER Signals are
rapid/specific and cause IMMEDIATE responses by the body.
True or False: Rapid signals from the nervous system cause immediate
responses by the body. - ANSWER True
Endocrine System [Basic Function] - ANSWER - The body's 'slow' chemical
communication system
- Communicates by chemical messages (HORMONES) that are secreted into
blood
- Involves glands for secretion
Nervous System [Basic Function] - ANSWER - The body's 'rapid'
communication system
- Employs electrical AND chemical means to send messages from cell to cell
- Involves nerves and neurons for transmission
3 Overlapping Functions of the Nervous System - ANSWER (1) Sensory Input
(2) Integration
,(3) Motor Output
Sensory Input [NS Function] - ANSWER Sensory receptors monitor changes
inside and outside of body
Integration [NS Function] - ANSWER CNS receives and interprets sensory
input and makes a decision for action
Motor Output [NS Function] - ANSWER Motor neurons elicit responses by
activating effector organs
2 Main Divisions of the Nervous System - ANSWER (1) Central Nervous
System (CNS)
(2) Peripheral Nervous System (PNS)
[Structure] Central Nervous System - ANSWER Brain and spinal cord
[Function] Central Nervous System - ANSWER Integrative and control centers
[Structure] Peripheral Nervous System - ANSWER Cranial nerves and spinal
nerves
*Everything else EXCEPT for the brain and spinal cord
[Function] Peripheral Nervous System - ANSWER Communication lines
between the CNS and the rest of the body
2 Divisions of the PNS - ANSWER (1) Sensory (afferent)
(2) Motor (efferent)
[Structure] Sensory (AFFERENT) Division of the PNS - ANSWER Somatic (skin)
and visceral (hollow organ lining) sensory nerve fibers
[Function] Sensory (AFFERENT) Division of the PNS - ANSWER Conducts
, impulses from *RECEPTORS to CNS*
[Structure] Motor (EFFERENT) Division of the PNS - ANSWER Motor nerve
fibers
[Function] Motor (EFFERENT) Division of the PNS - ANSWER Conducts
impulses from *CNS to EFFECTORS*, such as muscles and glands
Sensory division is [afferent/efferent], while motor division is
[afferent/efferent]. - ANSWER Sensory Division: AFFERENT
Motor Division: EFFERENT
Sensory division conducts impulses from _________ to _________, while motor
division does it from _________ to _________. - ANSWER Sensory Division: From
RECEPTORS to CNS
Motor Division: From CNS to EFFECTORS
2 Subdivisions of the PNS Motor Division - ANSWER (1) Somatic
(2) Automatic (ANS)
[Structure] Somatic Nervous System - ANSWER Somatic motor
(*VOLUNTARY*)
[Function] Somatic Nervous System - ANSWER Conducts impulses from *CNS
to SKELETAL MUSCLES*
[Structure] Autonomic Nervous System - ANSWER Visceral motor
(*INVOLUNTARY*)
[Function] Autonomic Nervous System - ANSWER Conducts impulses from
*CNS to CARDAIC MUSCLES, SMOOTH MUSCLES, and GLANDS*
