BIOS 252 Midterm Exam 2025 / BIOS252 Midterm Exam (Review and Essay Question Answer) Anatomy and Physiology II with Lab: Chamberlain College of Nursing
Neurotransmitter secreted by the adrenal medulla in response to stress. Also known as
adrenaline. Plays role in dreaming and regulating mood. Serve as hormone.
Self-propagating wave of electrical disturbance that travels along the surface of a neuron
membrane.
Neurotransmitter released by many PNS neurons and by some CNS neurons. It is both an
excitatory and an inhibitory neurotransmitter. Happens at synapses.
Basic functional (contractile) unit, separated from each other by dark bands called Z lines,
Contraction requires calcium and energy-rich ATP molecules
Term 2 of 99
Insertion
Skeletal muscle fibers (cells) within a muscle are arranged in bundles. may form one of five
patterns with respect to tendons.
Attachment of the muscle's other tendon to the moveable bone. Moves when muscle
contracts.
Attachment of a muscle's tendon to the stationary bone. Immovable.
Cell membranes that penetrate into the center of skeletal and cardiac muscle cells.
,Definition 3 of 99
the ability to shorten a muscle, requires energy, ATP rquired
Excitability
Extensibility
Contractibility
Elasticity
Term 4 of 99
Ligand-Gated Channel
Fascicles attach obliquely from many directions to several tendons.
Example: Deltoid muscle
open in response to binding of ligand (chemical) stimulus. Example:
Acetylcholine
Fascicles arranged on only one side of tendon. Example: Extensor Digitorum
Longus muscle
modulate neuronal transmission by either inhibiting or facilitating depolarization at the
presynaptic membrane.
Self-propagating wave of electrical disturbance that travels along the surface of a neuron
membrane.
Neurotransmitter released by many PNS neurons and by some CNS neurons. It is both an
excitatory and an inhibitory neurotransmitter. Happens at synapses.
They maintain homeostasis, form myelin, and provide support and protection for neurons.
, Term 7 of 99
muscles that make up the quadriceps femoris
rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius.
cell membranes that penetrate into the center of skeletal and cardiac muscle cells.
these forms of contractions can lead to tension headaches
It is found in the skin and in tubular arrangements that form part of the walls of small
arteries and veins and of hollow organs such as the stomach, intestines, uterus, and urinary
bladder. You cannot control this type of muscle.
Term 8 of 99
Graded Potential
the ability of the muscles to stretch; increase in length, ATP required
form myelin sheaths on axons in the CNS. Make sure to protect axons, and ensure
continuous power
Attachment of the muscle's other tendon to the moveable bone. Moves when muscle
contracts.
a type of electrical signal used for short distance communication only.
