ATI TEAS 7 All-in-One Practice Questions &
Answers Bundle
1. Oxytocin - ANSWER a hormone made by the hypothalamus and stored in
the posterior pituitary. One of its functions is to stimulate uterine
contractions during childbirth.
2. Pineal gland - ANSWER A small gland near the center of the brain that
secretes melatonin
3. Follicle-stimulating hormone (FSH) - ANSWER a hormone secreted by the
anterior pituitary gland that stimulates the development of ova or sperm.
Also stimulates the production of estrogen.
4. Estrogen - ANSWER steroid hormone; Female sex hormone released by
ovaries
5. Luteinizing hormone - ANSWER a hormone secreted by the anterior
pituitary gland that stimulates ovulation in ovaries and production of
testosterone in testes.
6. Ovaries - ANSWER female gonads where eggs are produced for
reproduction
7. Testosterone - ANSWER The steroid hormone that stimulates male
secondary sexual characteristics
8. Steroid hormones - ANSWER hormones derived from cholesterol. Their
lipid composition allows them to pass easily through cell membranes and
nuclear membranes. Affect transcription (expression of specific genes) in
their target cells.
Ex: increase in sex hormones influencing patterns of gene expression in
specific cells-puberty.
9. puberty - ANSWER a physiological period in which changes in hormone
levels cause a general "growth spurt" and development of secondary sex
characteristics.

10.nonsteroid hormones - ANSWER water-soluble hormones that can't pass b/t
the phospholipids of cell membranes. They bind to cell surface receptors.
Binding of the hormone to receptor triggers changes in the receptor that
signals molecules within the target cell. These internal signals initiate a
network of chemical reactions within the target cell, ultimately leading to
specific metabolic effects.
ex: thymosin stimulates the production of T cells
11.Thymus - ANSWER The lymphoid organ that produces T-cells.
12.parathyroid hormone (PTH) - ANSWER nonsteroid hormone secreted when
plasma calcium levels are low (hypocalcemia). Inhibits osteoblasts and
indirectly activates osteoclasts causing the reabsorption of calcium from
bones. Also works in the excretory system to increase plasma calcium levels
by inhibiting the kidney's ability to transfer calcium ions to urine.
13.Parathyroid - ANSWER An endocrine gland in the neck that produces
parathyroid hormone
14.Melatonin - ANSWER nonsteroid hormone secreted by the pineal gland to
maintain circadian rhythms.
15.Useful material moves from the filtrate back into the bloodstream -
ANSWER tubular reabsorption
16.Product of the liver that is stored by the gallbladder and is able to emulsify
lipids during digestion - ANSWER bile
17.Peripheral Nervous System (PNS) - ANSWER Consists of the extensive
network of spinal nerves carrying sensory or afferent information towards
the spinal cord and brain and motor or efferent information away from the
brain and spinal cord.
18.Afferent fibers - ANSWER transmit impulses from organs to CNS
19.Somatic nervous system - ANSWER voluntary control of skeletal muscles
ex: chewing food
20.Autonomic (visceral) nervous system - ANSWER involuntarily controls the
visceral muscles of organ systems like the digestive and cardiovascular
systems. Controls the contraction and relaxation of visceral reflexes.
, 3
ex: digestion, heartbeat
21.Sensory neurons - ANSWER gathers information and carries it to the CNS.
The senses gather the information that the sensory nervous system transmits
22.Motor nerves - ANSWER carry impulses away from the CNS to the
effectors
23.ventricles (brain) - ANSWER canals in the brain that contain cerebrospinal
fluid
24.Cerebrospinal fluid - ANSWER Fluid in the space between the meninges
that acts as a shock absorber that protects the central nervous system.
25.Cerebellum - ANSWER part of brain found at the very bottom (near neck)
of the skull and coordinates body movements, posture, and balance
26.Brainstem - ANSWER found between the thalamus and the spinal cord.
Lowest part of the brain. Supports unconscious functions like breathing,
heart rate, and blood pressure.
27.Cerebrum - ANSWER Largest part of the brain; responsible for interpreting
touch, speech, reasoning, and emotions
28.Cerebral cortex - ANSWER grey matter that surrounds the entire cerebrum
29.gyri - ANSWER ridges
30.Sulci - ANSWER shallow grooves
31.Fissures - ANSWER deep grooves in the brain
32.Frontal lobe - ANSWER processes high level cognitive skills, reasoning,
concentration, motor skills, language.
33.Parietal lobe - ANSWER integration site for visual perception and sensory
information such as touch, pain, and pressure
34.Temporal lobe - ANSWER Part of brain that controls hearing
, 4
35.Occipital lobe - ANSWER interprets visual information
36.Limbic system - ANSWER controls emotions and memory
37.Hypothalamus - ANSWER plays role in regulating the autonomic nervous
system. Primarily concerned with homeostasis and regulates activities such
as hunger, anger and pain
38.Amygdala - ANSWER this produces feelings such as anger, violence, fear,
anxiety
39.Thalumus - ANSWER sensory inputs come throught. Smell
40.synthesize proteins from amino acids, embedded in the rough ER. -

43.small organelle, moves material within a cell - ANSWER vesicles
44.consists of microtubules (made from proteins) that help shape and support
the cell - ANSWER cytoskeleton
45.liquid material within a cell - ANSWER cytosol
46.refers to cytosol and the structures within the plasma membrane of the cell -
