ISSA Strength and Conditioning
Chapter 2 questions and
answers already graded A+
(EVERYTHING YOU NEED TO
PASS)
CENTRAL NERVOUS SYSTEM (CNS): - answer The nervous
system cells that make up the brain and spinal cord.
PERIPHERAL NERVOUS SYSTEM (PNS): - answer The
nervous system cells that provide information to the brain
and spinal cord.
NEURON: - answer The nervous system cell that produces
action potentials to communicate with other neurons,
muscles, or glands.
GLIA: - answer A nervous system cell that protects and
nourishes neurons but that doesn't produce an action
potential.
ACTION POTENTIAL: - answer The electrical signal
produced by a neuron or muscle spindle.
Motor neurons - answer transmit commands from the
brain or spinal cord to muscles and glands.
, Sensory neurons - answer transmit information into the
brain and spinal cord to detect movement, sight, touch,
sound, and smell.
Interneurons - answer the most abundant in the nervous
system, create circuits between sensory or motor neurons
and transmit information between different parts of the
brain.
Dendrites - answer are branches of the cell body that act
as receivers, collecting information from other neurons.
cell body, - answer or soma, is the bulbous end of a
neuron that contains the nucleus (DNA). This is the part of
the neuron that integrates information and determines if
there's enough to create an action potential. The cell body
contains the nucleus, which is the center of the cell.
axon - answer is the transmitter portion, relaying signals
to other neurons, muscles, or organs. The axons that
travel from the spinal cord to the feet can be up to a
meter long but just 100 microns (a tenth of a millimeter)
wide.
MUSCLE SPINDLE: - answer A sensory receptor contained
in the muscle belly that detects changes in muscle length
and helps regulate contraction.
