What is the Peripheral Nervous System? - ANSWERS-Connects the
brain and spinal cord with receptors, muscles and glands and can be
broken down to afferent and efferent systems.
What is the Afferent System? - ANSWERS-Afferent conveys
information via neurons or nerve cells from senors in the periphery of
the body to the CNS. Conveys Incoming information about position and
tone from the muscle to the CNS.
What is the Efferent System? - ANSWERS-Also known as Motor
Neurons relay outgoing information from the CNS to the muscle cells.
How is the Efferent System Divided? - ANSWERS-Somatic and
Autonomic nervous systems
What is Autonomic System - ANSWERS-Transmit impulses to
involuntary muscles and glands
What is the Somatic System? - ANSWERS-Consists of efferent neurons
that transmit messages or impulses to voluntary skeletal muscles under
our conscious control (allows us to bend, move, twist, stretch).

What is a Diverging Circuit - ANSWERS-A single motor neuron in the
brain may stimulate several neurons in the spinal cord which in turn
stimulate several fibers in the skeletal muscle. - A single impulse from
the brain will contract several muscle fibers.
Name the 4 primary Nerve Branches - ANSWERS-Cervical Plexus
Brachial Plexus
Lumbar Plexus
Sacral Plexus
Protraction - ANSWERS-Forward movement of the shoulder girdle,
abduction of the scapulae
Retraction - ANSWERS-Backward movement of the shoulder girdle,
adduction of the scapulae
Pronation - ANSWERS-Rotating the forearm medially - palm down or
backwards
Supination - ANSWERS-Rotating the forearm laterally - palm up or
forward

Inversion - ANSWERS-Turning the sole of the foot inward (medially)
Eversion - ANSWERS-Turning the sole of the foot outward (laterally)
Tilt (which joints can tilt) - ANSWERS-Movements forward, backward
and to the side. The head, scapulae, and pelvis can tilt
Isometric - ANSWERS-Tension is developed in muscle w/o movement
at joint or change in muscle length. Tension remains constant (pressing
hands together)
Isokinetic - ANSWERS-A combination of isometric and isotonic.
Requires specialized equipment
Isotonic - ANSWERS-Involves movement at the joint - concentric -
shortening contraction and eccentric - lengthening contraction
Why is all movement in the water (without any equipment) concentric? -
ANSWERS-Water is resisted in all planes of movement and in all

directions of movement by the water's viscosity and drag. Water can
help promote muscle balance.
What is resisted movement? - ANSWERS-Any part in the ROM of the
exercise where additional resistance is created by moving against a force
(gravity, buoyancy, properties/mechanics of equipment) usually a
concentric action
What is an assisted movement - ANSWERS-Any part of the ROM of the
exercise that is facilitated by the forces of gravity or buoyancy or by the
properties/mechanics of equipment - usually an eccentric action
What is ATP-PCr System? - ANSWERS-Supplies the working muscle
with an immediate source of energy.
Name three primary options available for the endurance component of
an aquatic workout. - ANSWERS-1. Cardiorespiratory Endurance
Training
2. Muscular Fitness Training
3. Muscular Flexibility and ROM Training
