HESI - Anatomy & Physiology practice test with Certified Solutions
What are the four fundamental tissues ? ✔✔Epithelial,connective,muscle,nervous
Epithelial Tissue ? ✔✔Cover, line, and protect the body and its internal organs.
Connective tissue ? ✔✔Is the framework of the body which provides support and structure for the organs.
Nerve Tissue ? ✔✔Composed of neurons and connective tissue cells (Neuroglia).
Muscle Tissues ? ✔✔Have the ability to contract or shorten
Function of the nucleus ? ✔✔Carries DNA
Function of Ribosomes ? ✔✔Important for the synthesis of proteins
- / 3
Mitosis ? ✔✔DNA is duplicated and distributed evenly between two daughter cells.
Meiosis ? ✔✔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 ? ✔✔Skin
How many layers does the skin consist of ? ✔✔Two : Dermis & Epidermis
Epidermis ? ✔✔The outermost protective layer of dead keratinized epithelial cells.
Dermis ? ✔✔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 ? ✔✔Stratum corneum, stratum lucidum, stratum granulosum, and stratum germinativum (Inner most layer).
- / 3
What are the two parts of the Germinativum (Innermost layer of the Epidermis) ? ✔✔Stratum basale & Stratum spinosum
Where does mitosis occur ? ✔✔Stratum Germinativum
Epidermal cells contain the protein pigment called _______ ? ✔✔Melanin
What is the function of melanin ? ✔✔Protects against radiation from the sun
What is the dermis composed of ? ✔✔fibrous connective tissue,
What are the two types of sweat glands ? ✔✔Eccrine & Appocrine
What is eccrine ? ✔✔regulates body temperature by releasing a watery secretion that evaporates from the surface of the skin.
What is appocrine ? ✔✔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.
