HESI - ANATOMY &PHYSIOLOGY PRACTICE TEST
What are the four fundamental tissues? (ANS- Epithelial,connective,muscle,nervous
Epithelial Tissue ?
(ANS-
... [Show More] 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. [Show Less]
