ECPI A&P 1 Final Exam 2025 Questions
and Correct Answers Rated A+
Adipocytes -ANSWER-fat cells
Erythrocytes -ANSWER-red blood cells (RBC); no nucleus, contain
hemoglobin which carries oxygen
Aponeurosis -ANSWER-strong sheet of tissue that acts as a tendon to
attach muscles to bone
What is the matrix composed of? -ANSWER-fibrous proteins and
ground substance
What are the layers of the bone? -ANSWER-periosteum, compact
bone, spongy bone, bone marrow
Interphase -ANSWER-Cell grows, performs its normal functions, and
prepares for division; consists of G1, S, and G2 phases
Prophase -ANSWER-Chromosomes become visable, nuclear envelop
dissolves, spindle forms
Metaphase -ANSWER-second phase of mitosis, during which the
chromosomes line up across the center of the cell
Anaphase -ANSWER-the third phase of mitosis, during which the
chromosome pairs separate and move toward opposite poles
Telophase -ANSWER-phase of mitosis in which the distinct individual
chromosomes begin to spread out into a tangle of chromatin
, Cytokinesis -ANSWER-division of the cytoplasm to form two separate
daughter cells
muscle spindles -ANSWER-receptors sensitive to change in length of
the muscle and the rate of that change
Golgi tendon organs -ANSWER-receptors that sense movement of the
tendons, which connect muscle to bone
tectorial membrane -ANSWER-A membrane located above the basilar
membrane; serves as a shelf against which the cilia of the auditory
hair cells move
Nociceptors -ANSWER-pain receptors
EPSP -ANSWER-Excitatory postsynaptic potential; a slight
depolarization of a postsynaptic cell, bringing the membrane potential
of that cell closer to the threshold for an action potential.
IPSP -ANSWER-Inhibitory postsynaptic potential; a slight
hyperpolarization of the postysynaptic cell, moving the membrane
potential of that cell further from threshold.
graded potential -ANSWER-a shift in the electrical charge in a tiny
area of a neuron
action potential -ANSWER-a neural impulse; a brief electrical charge
that travels down an axon
resting potential -ANSWER-The difference in electric charge between
the inside and outside of a neuron's cell membrane
