Nervous
system learning outcomes:
-
Identify
and give functions for: dendrite, cell body, axon
-
Differentiate
among sensory, motor and interneurons with respect to structure and function
-
Explain
the transmission of a nerve impulse through a neuron, using the following
terms:
o
Resting
and action potential
o
Depolarization
and repolarization
o
Refractory
period
o
Sodium
and potassium pump
o
Threshold
value
-
Relate
the structure of a myelinated nerve fibre to the speed of impulse conduction
with reference to myelin sheath, Schwann cell, node of Ranvier
-
Identify
the major components of a synapse, including
o
Synaptic
ending
o
Presynaptic
and postsynaptic membranes
o
Synaptic
cleft
o
Synaptic
vesicle
o
Calcium
ions
o
Neurotransmitters
o
receptor
o
enzymes
(ex. Acetylcholinesterase)
-
explain
the process by which impulses travel across a synapse
-
describe
the structure of a reflex arc
-
compare
the locations and functions of the central and peripheral nervous systems
-
identify
and give functions for each of the following parts of the brain
o
medulla
oblongata
o
cerebrum
o
thalamus
o
cerebellum
o
hypothalamus
o
pituitary
gland
o
corpus
callosum
o
meninges
-
explain
how the hypothalamus and pituitary gland interact as the neuroendocrine control
center
-
differentiate
between the autonomic and somatic nervous systems
-
differentiate
between the sympathetic and parasympathetic divisions of the autonomic system
o
with
reference to effect on body functions including heart rate, breathing rate,
pupil size, digestion and overall response (“fight or flight” versus “rest and
digest”)
