(forearm); ulna (forearm); phalanges (fingers and toes); tibia (lower leg);
fibula (lower leg
◍ posterior pituitary gland.
Answer: is made of nervous tissue
◍ neuron differ from a nerve.
Answer: neuron is an individual cell;nerve is a group of axons coming off a
group of neuron
◍ functions of the epidermis.
Answer: a. Protection from Physical Damageb. Protection from Pathogensc.
Protection from UV Lightd. Water Retentione. Vitamin D Synthesis
◍ thymus gland function.
Answer: produces the hormone thymosin
◍ Mixed Nerves (PNS).
Answer: contain both sensory and motor neurons so they can transmit
signals to and from the CNS

Answer: cells that destroy pathogens and remove debris
◍ Refractory or recovery period (phase of action potential).
Answer: super negative before original negative state (resting potential)
◍ myelin sheath.
, Answer: the lipid layer around the axon of a neuron; helps speeds up the rate
at which they can send information to other neurons down the axon
◍ progesterone.
Answer: a hormone secreted from corpus luteum in the ovaries that plays an
important role in pregnancy

Answer: allow little or no movement at the joint (ex: skull, rib cage)
◍ Examples of sesamoid bones.
Answer: patella (kneecap)
◍ FSH.
Answer: causes the production of sex cells in males and females
◍ repolarization (phase of action potential).
Answer: goes negative
◍ Macrophages.
Answer: a type of monocyte (white blood cell) found in body tissue that
destroys damaged red blood cells, bacteria, or viruses
◍ kidney location.
Answer: abdominal cavity behind internal organs
◍ erection.
