HESI Anatomy and Physiology
Study Q & A
What is histology?
The study of tissues.
What is a tissue?
A group of cells that act together to perform a specific function.
What are the fundamental tissues?
Epithelial, Connective, Muscle, Nerve
(Mnemonic: Elephants Can Make News)
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.
, 3|Page
What are the layers of the epidermis?
Corneum, Lucidum, Granulosum, Germinativum (basale & spinosum).
Mnemonic: Candy Lions Growl Great.
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?
Eccrine and apocrine.
What do eccrine 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.
, 4|Page
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, and joints.
What are the functions of the skeletal system?
Support, movement, blood cell formation, protection of internal organs,
detoxification, muscle attachment, mineral storage.
