ATI TEAS 7 Nursing Science Exam 2025/2026 – Exam Questions with
Answers | Complete Study Guide | Graded A+ | Guaranteed Pass
what cause the continuation of inhibition of the impulse - ANSWER=the neurotransmitters
secreted into the synapse are picked up by the next cell
spinal nerves - ANSWER=are bundles of nerve fibers axons and dendrites and therefore can
carry both afferent and efferent impulses when an efferent axon terminal synapses with in a cell
stimulation of m contraction occurs
muscles - ANSWER=consist of bundles of m fibers or cells contain countless smaller myofibrils
myofibrils - ANSWER=have two types of contractile protein filaments: thinner actin and thicker
myosin -arranged in overlapping bands
sacromere - ANSWER=Basic contracting unit of muscle cell consits of actin and myosin filaments
between z-lines in a muscle cell
muscle strain - ANSWER=an injury to accompany supporting ligaments and tendons of a muscle
chromosome - ANSWER="chapter" A threadlike, gene-carrying structure found in the nucleus.
Each chromosome consists of one very long DNA molecule and associated proteins.
gene - ANSWER="sentence" sequence of DNA that codes for a protein and thus determines a
trait
,2|Page
nucleotide - ANSWER="letter" A building block of DNA, consisting of a five-carbon sugar
covalently bonded to a nitrogenous base and a phosphate group.
Codon - ANSWER=" word" A specific sequence of three adjacent bases on a strand of DNA or
RNA that provides genetic code information for a particular amino acid
Periodic Period - ANSWER=number of shells It's the element from left to right. The horizontal
rows. show increase in energy levels
periodic table groups - ANSWER=are the columns. number of valence electrons
on the periodic table shell labels and their max number of electrons - ANSWER=s-2,
p-6
d-18
f-32
isotopes - ANSWER=Atoms of the same element that have different numbers of neutrons
Atoms are neutral - ANSWER=equal number of protons and electrons
ion - ANSWER=An atom or group of atoms that has a positive or negative charge.
,3|Page
ionic bond - ANSWER=A chemical bond resulting from the attraction between oppositely
charged ions.
amyotrophic lateral sclerosis (ALS) - ANSWER=aka Lou Gegrig's disease (Hawking); a progressive,
motor neurons degenerate and die leading to loss of voluntary muscle movement
what are the 3 main parts of a cell - ANSWER=plasma membrane, cytoplasm, nucleus
Path of cardiac conduction system - ANSWER=sa node, av node, bundle of his, bundle branches,
purkinje fibers.
What is the cytoplasm of a cell - ANSWER=semi fluid substance inside the membrane
does the nucleus have a single or double membrane - ANSWER=the nucleus has a double
membrane
plasma membrane - ANSWER=A selectively-permeable phospholipid bilayer forming the
boundary of the cells with proteins that act as gatekeepers
Rough Endoplasmic Reticulum - ANSWER=continuous with the outer membrane of the nucleus
,has parallel sacs covered with ribosomes
, 4|Page
Smooth Endoplasmic Reticulum - ANSWER=has no ribosomes, functions as site of lipid
production and storage
once proteins are made on ribosomes of the rough E.R. what happens next? - ANSWER=they
are packaged in membrane into vesicles an transport to the Golgi complex- the protein vesicles
fuse with the golgi where they are modified and transported where needed
golgi - ANSWER=shipping part of the cell
what are the 4 types of tissues - ANSWER=epithelial, connective, muscle, nervous
What does epithelial tissue cover? - ANSWER=covers body surfaces, lines body cavities serves as
protective barrier
What does connective tissue do? - ANSWER=connects other tissues to each other and binds and
supports body parts
What does muscle tissue do? - ANSWER=move the body and its contents by contraction
What does the nervous system do? - ANSWER=receive stimuli and communicates through
electrical impulses with the rest of the body
what organ is made up of all 4 tissue types - ANSWER=skin
