ECPI BIO 111 EXAM 4 (10-12)
with verified answers
1. Nervous System Function:: sends and receives information;
sensory receptors detect changes, and they are highly
specialized; making decisions either voluntary or involuntary;
stimulates muscles and glands to respond; maintains
homeostasis; acts as a center for thought, learning, and
memory
2. master regulatory system: nervous system
3. Main Cell Types of the Nervous System:: Neurons and Neuroglia
4. Neurons/Nerve Cells: Cells that respond quickly to
changes/stimuli
5. neurons release:: neurotransmitters
6. Neuroglia: Cells that protect, support, insulate, and nourish
neurons
,7. neurons conduct:: electrical impulses
8. Nervous System Structure:: Central Nervous System (CNS)
and Peripheral Nervous System (PNS)
9. Central Nervous System: Brain and Spinal Cord
10.Peripheral Nervous System: Connects CNS to other body
parts; Consists of Cranial and Spinal Nerves
11.Two Subdivisions of the PNS: Afferent (Sensory) and Efferent
(Motor)
12.Afferent (Sensory) Division: Division of sensory receptors that
perform senso- ry function (detect changes); receptors
convert information into impulses; impulses conducted along
peripheral nerves to CNS for integration
13.Efferent (Motor) Division: Division that includes neurons that
transmit impulses from the CNS to effectors perform motor
function; effectors are muscles or glands outside the nervous
system
14.Two Subdivisions of the Efferent Division: Somatic and Autonomic
15.Somatic Division: Transmits voluntary commands to skeletal
, muscles
16.Autonomic Division: Transmits involuntary commands to
viscera
17.Neurons: generate and transmit the nerve impulse; vary
in size; may differ in length, number, and size of axons and
dendrites
18.primary cell type: neurons
19.Neurons share the following structural features:: Cell
body/Soma, Den- drites, Axon
20.Cell body/Soma: Contains nucleus, cytoplasm, organelles,
neurofilaments, chromatophilic substance, and receptive
surface for signal
21.Dendrites: Branched receptive surfaces for signal
22.Axon: Transmits impulses and releases neurotransmitters
to another neuron or effector; can be myelinated or
unmyelinated
23.Structural features of Axons:: Axon Hillock, Collaterals,
Axon Terminal, Synaptic Knob
, 24.Axon Hillock (Trigger Zone): Cone-shaped area of cell body
from which axon arises
