What is the function of epithelial cells?
Correct answer: Cover, line, and protect the body and the internal organs.
What is the function of connective tissue?
Correct answer: Framework of the body. Provides support and structure to organs.
What is neuroglia?
Correct answer: The neurons and connective tissue cells that compose nerve tissue.
What ability does muscle tissue have?
Correct answer: Ability to contract and shorten.
,What is muscle tissue classied as?
Correct answer: Voluntary(skeletal muscles) and involuntary(smooth & cardiac)
What is meiosis?
Correct answer: The cell division that takes place in the gonads, i.e. the ovaries and testes.
What two layers compose the skin?
Correct answer: Epidermis and dermis.
What is the epidermis?
Correct answer: The outermost protective layer of dead keratinized epithelial cells.
What is the dermis?
Correct answer: The underlying layer of connective tissue with blood vessels, nerve
endings, and the associated skin tissues.
What are the layers of the epidermis?
Correct answer: Corneum
Lucidum
Granulosum
Germivatum ( basale & spinosum)
Mnemonic: Candy Lions Growl Great.
What does the protein pigment melanin protect against?
Correct answer: Radiation from the Sun
, What is the dermis composed of?
Correct answer: Fibrous connective tissue with nerve endings, blood vessels, sensory
nerve endings, hair follicles, and glands.
What are the 2 types of sweat glands?
Correct answer: ecrine & apocrine
What do ecrine sweat glands produce?
Correct answer: Sweat. Regulate body temperature.
What do apocrine sweat glands produce?
Correct answer: Secretions contain bits of cytoplasm from cells, attracting bacteria that
produces body odor.
What do sebaceous glands secrete?
Correct answer: They secrete sebum through the hair follicles, which lubricates the skin
and prevents drying.
What secretion produces oil?
Correct answer: Holocrine secretion.
What are sebaceous glands prone to during adolescence?
Correct answer: Becoming clogged and attracting bacteria.
What protein composes the hair and skin?
Correct answer: Keratin
