HESI - Anatomy & Physiology practice test
What are the four fundamental tissues ?
(ANS- Epithelial,connective,muscle,nervous
Epithelial Tissue ?
(ANS- Cover, line, and protect the body and its internal organs.
Connective tissue ?
(ANS- Is the framework of the body which provides support and structure for the
organs.
Nerve Tissue ?
(ANS- Composed of neurons and connective tissue cells (Neuroglia).
Muscle Tissues ?
(ANS- Have the ability to contract or shorten
Function of the nucleus ?
(ANS- Carries DNA
Function of Ribosomes ?
(ANS- Important for the synthesis of proteins
Mitosis ?
(ANS- DNA is duplicated and distributed evenly between two daughter cells.
,Meiosis ?
(ANS- Cell division where 46 chromosomes are reduced to 23 so they zygote has
the correct number of chromosomes.
What is the largest organ in the body ?
(ANS- Skin
How many layers does the skin consist of ?
(ANS- Two : Dermis & Epidermis
Epidermis ?
(ANS- The outermost protective layer of dead keratinized epithelial cells.
Dermis ?
(ANS- The underlying layer of connective tissue with blood vessels, nerve
endings, and the associated skin structures.
What are the layers of the Epidermis from outer layer to inner layer ?
(ANS- Stratum corneum, stratum lucidum, stratum granulosum, and stratum
germinativum (Inner most layer).
What are the two parts of the Germinativum (Innermost layer of the Epidermis) ?
(ANS- Stratum basale & Stratum spinosum
, Where does mitosis occur ?
(ANS- Stratum Germinativum
Epidermal cells contain the protein pigment called _______ ?
(ANS- Melanin
What is the function of melanin ?
(ANS- Protects against radiation from the sun
What is the dermis composed of ?
(ANS- fibrous connective tissue,
What are the two types of sweat glands ?
(ANS- Eccrine & Appocrine
What is eccrine ?
(ANS- regulates body temperature by releasing a watery secretion that evaporates
from the surface of the skin.
What is appocrine ?
(ANS- secretion that contains bit of cytoplasm from the secreting cells. This cell
bacteria attracts bacteria, and the presence of bacteria on the skin results in body
odor.
What does the appendages of the skin contain ?
(ANS- hair and nails
