review questions and correct answers
a cut through the body that passes perpendicular to the long axis of the body and
divides the body into a superior and inferior section is known as a - ANS>>transverse
section
glands that discharge an oily secretion into hair follicles are - ANS>>sebaceous glands
action potentials are conducted into the skeletal muscle fiber by - ANS>>transverse
tubules
the plate of bones found in spongy bone are called - ANS>>trabeculae
how would blocking the activity of acetylchlinesterase affect skeletal muscle? - ANS>>it
would cause spastic paralysis( muscles are contracted and unable to relax
interactions between actin and myosin filaments of the sarcomere are responsible for -
ANS>>muscle contraction
the layer of the epidermis that contains cells undergoing division is the - ANS>>stratum
germinativum
the pigments melanin - ANS>>is produced by cells called melanocytes
the watery medium the surrounds our cells is known as - ANS>>interstitial fluid
in the elderly, blood supply to the dermis is reduced and sweat glands are less active.
this combination of factors would most affect - ANS>>the ability to thermoregulate
when stress is applied to a bone - ANS>>the minerals in the bone produce a weak
electrical field that activates osteoblasts
an immovable joint is a - ANS>>synarthrosis
the layer of the skin that provides protection against bacteria as well as chemical and
mechanical injuries is the - ANS>>epidermis
the molecule ATP - ANS>>is formed from ADP and phosphate, contains high energy
covalent bonds, is the most important high energy compound in human cells, provides
energy for cellular reactions when the bond attaching the last phosphate to the molecule
is broken
cross-bridges are located on - ANS>>myosin molecules
, during muscle contraction - ANS>>ATP is hydrolyzed to ADP and phosphate, actin and
myosin filaments slide together, the sarcomere becomes shorter, calcium concentration
in the sarcomere increases
during the recovery period after muscular exercise the body's need for oxygen is
increased because - ANS>>oxygen is required to metabolize the lactic acid produced
during exercise
the following is a list of several levels of organization that make up the human body -
ANS>>molecule,cell,tissue,organ,organ system, organism
osteolysis is the process of - ANS>>bone matrix is dissolved and minerals are released
into the blood
serous membranes is - ANS>>secrete lubricating fluid and are found lining cavities and
covering organs without openings to the outside of the body
most of the chemical reactions involved in cellular metabolism are regulated by -
ANS>>enzymes
intramembranous ossification occurs - ANS>>in the skull of the fetus
each of the following is a primary tissue type except one.identify the exception -
ANS>>adipose tissue
depolarization of the sarcolemma at the myoneural junction occurs when -
ANS>>acetylcholine binds to receptors on the sacrolemma
parathyroid hormone - ANS>>stimulates osteoclast activity, increases the rate of
calcium absorption from the intestine, decreases the rate of calcium excretion by the
kidneys, raises the level of calcium ion in the blood
water molecules and small ions enter a cell through - ANS>>channels (pores) in some
integral proteins
the central canal of an osteon contains - ANS>>blood vessels
a muscle that is stimulated so frequently that the relaxation phase is completely
eliminated is said to exhibit - ANS>>complete tetany
which of the following happens if body temperature rises above normal ? - ANS>>blood
flow to the skin increases
vitamin D is necessary for - ANS>>absorption of calcium and phosphate ions
