Which cells excrete pepsinogen?
chief cells of the stomach. *Pepsin is an enzyme in the stomach that helps break down proteins into smaller peptides
Sensory neurons
Carry an AFFERENT IMPULSE to the brain
Which organ is responsible for a majority of digestion?
Small intestine
Which NERVE structure TRANSMITS impulses to other cells?
axon
Contraction occurs when
Thin actin filaments SLIDE PAST thicker myosin filaments CAUSING the sarcomere unit to shorten
Inflammation
Innate immune response resulting in redness, swelling, heat, and pain - R.S.H.P
The ENDOCRINE SYSTEM produces what RESPONSE?
SLOW INITIATING, PROLONGED RESPONSE on other body systems
What is the INTERGRATION center between ENDOCRINE and NERVOUS system?
Hypothalamus *Hypothalamus -Small cone shaped that is located at the base of the brain and near the Pituitary gland
ENDOcrine glands
Releases chemical substances directly INTO the BLOODSTREAM or TISSUES of the BODY
EXOcrine glands
RELEASE chemicals OUTSIDE the body OR to ANOTHER SURFACE within the body
What GLAND has an EXOCRINE FUNCTION and AIDS in BLOOD GLUCOSE REGULATION?
Pancreas *Pancrease large gland that helps digestion and blood regulation
Epidermis
OUTER LAYER of the SKIN MADE of EPITHELIAL TISSUE
Hypodermis
Lowest layer of skin
Osteo-clast
Bone cells that perform calcium mineral reabsorption
Dermis
MIDDLE LAYER of skin made of connective tissue
Osteo-blasts
Synthesize bones, the secretions allow for mineralization
Osteocytes
Star shaped bone cell. Maintains structure. Senses physical stress.
Osteons
CYLINDRICAL STRUCTURE comprised of compact bone tissue that SURROUND the HAVERSIAN CANAL
B-cells
LYMPHOCTYES that MAKE antibodies in response to antigens.
Spongy bone
FEWER OSTEONS than compact bone, where RED BONE is FORMED.
YELLOW MARROW is LOCATED in?
LONG ADULT BONES in the MEDULLARY CAVITY
Helper T cells
Secrete INTERLUKENS that trigger the action of other cells.
Cytotoxin T cell
ATTACKS foreign cells, activated by interlukens
Transverse plane
Located at midsection, separates superior and inferior sections
