/.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)

/.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.
