Abductor
A muscle that moves a limb away from the cebter of the body
Absorption
The process by which substances are taken up into or across tissues
Acetylcholine
A neurotransmitter found throughout the nervous system (somatic motor neurons,
preganglionic parasympathetic and sympathetic nerves, and postganglionic parasympathetic
neurons); metabolized by acetylcholinesterase.
Acrosome
, The large vesicle at the head of a sperm cell containing enzymes that degrade the ovum cell
membrane to allow fertilization
Actin
A protein found in the cytoskeleton and muscle cells; it is the principle constituent of the thin
filaments and microfilaments
Action potential
An abrupt change in the membrane potential of a nerve or muscle caused by changes in
membrane ionic permeability; results in a conduction of an impulse in nerves or contraction in
muscles
Active immunity
An immune response (antibody production or cellular immunity) acquired in response to
exposure to an antigen
Active site
Substrate-binding region of an enzyme
Adaptation
The development of characteristics that enable an organism to survive and reproduce in its
habitat
