HESI A2 Anatomy and Physiology
1. What is histology?: The study of tissues
2. What is a tissue?: A group of cells that act together to perform a specific function.
3. What are the fundamental tissues?: Epithelial
Connective
Muscle
Nerve

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 involuntary(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.
12. What is the dermis?: 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)

14. What does the protein pigment melanin protect against?: Radiation from the Sun
15. What is the dermis composed of?: Fibrous connective tissue with nerve endings, blood vessels,
sensory nerve endings, 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.
