1. What is histology? The study of tissues
2. What is a tissue? A group of cells that act together to per-
form a specific function.
3. What are the fundamental tissues? Epithelial
Connective
Muscle
Nerve
(Elephants Can Make News)
4. What is the function of epithelial cells? Cover, line, and protect the body and the
internal organs.
5. What is the function of connective tissue? Framework of the body. Provides support
and structure to organs.
6. What is neuroglia? The neurons and connective tissue cells
that compose nerve tissue.
7. What ability does muscle tissue have? Ability to contract and shorten.
8. What is muscle tissue classified as? Voluntary(skeletal muscles) and involun-
tary(smooth & cardiac)
9. What is meiosis? The cell division that takes place in the
gonads, i.e. the ovaries and testes.
10. What two layers compose the skin? Epidermis and dermis.
11. What is the epidermis? The outermost protective layer of dead
keratinized epithelial cells.

The underlying layer of connective tissue
with blood vessels, nerve endings, and
the associated skin tissues.
13. What are the layers of the epidermis? Corneum
Lucidum
Granulosum
Germivatum ( basale & spinosum)
Mnemonic: Candy Lions Growl Great.
14. What does the protein pigment melanin Radiation from the Sun
protect against?
15. What is the dermis composed of? Fibrous connective tissue with nerve end-
ings, blood vessels, sensory nerve end-
ings, hair follicles, and glands.
16. What are the 2 types of sweat glands? ecrine & apocrine
17. What do ecrine sweat glands produce? Sweat. Regulate body temperature.
18. What do apocrine sweat glands produce? Secretions contain bits of cytoplasm from
cells, attracting bacteria that produces
body odor.
19. What do sebaceous glands secrete? They secrete sebum through the hair fol-
licles, which lubricates the skin and pre-
vents drying.
