function.
What are the fundamental tissues? -ANSWER Epithelial
Connective
Muscle
Nerve
(Elephants Can Make News)
What is the function of epithelial cells? -ANSWER Cover, line, and protect the body and
the internal organs.
What is the function of connective tissue? -ANSWER Framework of the body. Provides
support and structure to organs.
What is neuroglia? -ANSWER The neurons and connective tissue cells that compose
nerve tissue.
What ability does muscle tissue have? -ANSWER Ability to contract and shorten.
What is muscle tissue classified as? -ANSWER Voluntary(skeletal muscles) and
involuntary(smooth & cardiac)
What is meiosis? -ANSWER The cell division that takes place in the gonads, i.e. the
ovaries and testes.
What two layers compose the skin? -ANSWER Epidermis and dermis.
What is the epidermis? -ANSWER The outermost protective layer of dead keratinized
epithelial cells.
What is the dermis? -ANSWER The underlying layer of connective tissue with blood
vessels, nerve endings, and the associated skin tissues.
What are the layers of the epidermis? -ANSWER Corneum
, Lucidum
Granulosum
Germivatum ( basale & spinosum)
Mnemonic: Candy Lions Growl Great.
What does the protein pigment melanin protect against? -ANSWER Radiation from the
Sun
What is the dermis composed of? -ANSWER Fibrous connective tissue with nerve
endings, blood vessels, sensory nerve endings, hair follicles, and glands.
What are the 2 types of sweat glands? -ANSWER ecrine & apocrine
What do ecrine sweat glands produce? -ANSWER Sweat. Regulate body temperature.
What do apocrine sweat glands produce? -ANSWER Secretions contain bits of
cytoplasm from cells, attracting bacteria that produces body odor.
What do sebaceous glands secrete? -ANSWER They secrete sebum through the hair
follicles, which lubricates the skin and prevents drying.
What secretion produces oil? -ANSWER Holocrine secretion.
What are sebaceous glands prone to during adolescence? -ANSWER Becoming
clogged and attracting bacteria.
What protein composes the hair and skin? -ANSWER Keratin
What makes the body's framework? -ANSWER Bone, cartilage, ligaments & joints.
What are the functions of the skeletal system? -ANSWER Support, movement, blood cell
formation, protection of internal organs, detoxification, muscle attachment, mineral
storage. *A MIME BATHED SEALS SINGING "MY PONY"*
How are bones classified? -ANSWER By shape.
Long
Short
flat
irregular
sesamoid
*LEMURS SING SALSA FOR INDIANS*
What is the name for the cells that compose compact bone? -ANSWER Osteoblasts
What occurs to osteoblasts when they become fixed in the dense bone matrix? -
ANSWER They stop dividing but continue to maintain body tissues as osteocytes.
