What is the function of epithelial cells? - ✅✅Cover, line, and protect the body and the internal
organs.
What is the function of connective tissue? - ✅✅Framework of the body. Provides support and
structure to organs.
What is neuroglia? - ✅✅The neurons and connective tissue cells that compose nerve tissue.
What ability does muscle tissue have? - ✅✅Ability to contract and shorten.
What is muscle tissue classified as? - ✅✅Voluntary(skeletal muscles) and involuntary(smooth &
cardiac)
What is meiosis? - ✅✅The cell division that takes place in the gonads, i.e. the ovaries and testes.
What two layers compose the skin? - ✅✅Epidermis and dermis.
,What is the epidermis? - ✅✅The outermost protective layer of dead keratinized epithelial cells.
What is the dermis? - ✅✅The underlying layer of connective tissue with blood vessels, nerve endings,
and the associated skin tissues.
What are the layers of the epidermis? - ✅✅Corneum

What does the protein pigment melanin protect against? - ✅✅Radiation from the Sun
What is the dermis composed of? - ✅✅Fibrous connective tissue with nerve endings, blood vessels,
sensory nerve endings, hair follicles, and glands.
What are the 2 types of sweat glands? - ✅✅ecrine & apocrine
What do ecrine sweat glands produce? - ✅✅Sweat. Regulate body temperature.
What do apocrine sweat glands produce? - ✅✅Secretions contain bits of cytoplasm from cells,
attracting bacteria that produces body odor.
What do sebaceous glands secrete? - ✅✅They secrete sebum through the hair follicles, which
lubricates the skin and prevents drying.
What secretion produces oil? - ✅✅Holocrine secretion.
, What are sebaceous glands prone to during adolescence? - ✅✅Becoming clogged and attracting
bacteria.
What protein composes the hair and skin? - ✅✅Keratin
What makes the body's framework? - ✅✅Bone, cartilage, ligaments & joints.
What are the functions of the skeletal system? - ✅✅Support, movement, blood cell formation,
protection of internal organs, detoxification, muscle attachment, mineral storage. *A MIME BATHED

What is the name for the cells that compose compact bone? - ✅✅Osteoblasts
What occurs to osteoblasts when they become fixed in the dense bone matrix? - ✅✅They stop
dividing but continue to maintain body tissues as osteocytes.
How many bones make up the axial skeleton? - ✅✅28 bones of the skull. 14-facial, 14-cranium.
How many bones make the facial skeleton? - ✅✅2 nasal bones
