noting or pertaining to a situation in which one organ performs part of the functions normally performed by another
antagonist
a muscle that acts in opposition to another
assimilate
to convert food to substances suitable for incorporation into the body and its tissues
fatigue
temporary diminution of the irritability or functioning of organs, tissues, or cells after excessive exertion or stimulation
sensitive
having a low threshold of sensation or feeling
apparatus
a group of structurally different organs working together in the performance of a particular function; the digestive apparatus
respond
to exhibit some action or effect as if in answer
impulse
a progressive wave of excitation over a nerve or muscle fiber that has a stimulating or inhibitory effect
action
a change in organs, tissues, or cells leading to performance of a function like muscular contraction
contraction
the change in a muscle by which it becomes thickened and shortened
eliminate
to void or expel from an organism
antagonism
an opposing action, as by one muscle in relation to another
sensation
ability to perceive stimuli
consensual
involuntarily correlative with a voluntary action, as the contraction of the iris when the eye is opened
migrate
to move from one region of the body to another, as in embryonic development
bile
a bitter, alkaline, yellow or greenish liquid, secreted by the liver, that aids in absorption and digestion
menopause
the period of permanent cessation of menstruation
continence
the ability to voluntarily control urinary and fecal discharge
reaction
action in response to a stimulus of a system, a nerve or a muscle
synapse
a region where nerve impulses are transmitted and received in the brain
sensitivity
the ability of an organism or part of an organism to react to stimuli; degree of susceptibility to stimulation
involuntary
acting independently of or done or occurring without volition
automatic
occurring independently of volition, as certain muscular actions; involuntary
sensory
noting a structure for conveying an impulse that results or tends to result in sensation such as a nerve
excite
to stimulate to functional activity
responsive
acting as a result to some stimulus
basal
indicating a standard low level of activity of an organism, as during total rest
agonist
a contracting muscle whose action is opposed by another muscle
menarche
the first menstrual period; the establishment of menstruation
reflex
pertaining to an involuntary response to a stimulus, in which the nerve impulse from a receptor is transmitted inward to a nerve center, then transmitted outward to an effector
arterial
pertaining to the blood in the pulmonary vein, having been oxygenated during its passage through the lungs and being normally bright red
histamine
a histidine-derived amine compound that is released mainly by damaged mast cells in allergic reactions, causing dilation and permeability of blood vessels and lowering blood pressure
receptor
an end organ or a group of end organs of sensory or afferent neurons, specialized to be sensitive to stimulating agents
calcification
the deposition of lime or insoluble salts of calcium and magnesium
heartbeat
a pulsation of the heart, including one complete systole and diastole
kinesis
the movement of an organism in response to a stimulus such as light
action potential
the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals
biorhythm
an innate periodicity in an organism's physiological processes like sleep and wake cycles
REM sleep
a period of sleep during which most dreaming occurs as the eyes move under closed lids and the skeletal muscles are deeply relaxed
pulmonary circulation
the circulation of blood from the heart to the lungs for oxygenation and back to the heart
biological clock
an innate mechanism of the body that regulates its rhythmic and periodic cycles
vital function
any function of the body that is essential for life
postsynaptic
being or occurring on the receiving end of a discharge across the synapse
presynaptic
being or occurring on the transmitting end of a discharge across a synapse
oxygen debt
the body's oxygen deficiency resulting from strenuous physical activity
prepuberty
the period of life just prior to sexual maturation
disdain
to think unworthy of notice, response, etc.; consider beneath oneself
ideogram
a written symbol, as 7, =, logogram.
viable
having the ability to grow, expand, develop, etc.
