BI 231/241 Exam 1 Review - Tissue
Which morphological adaptations of neurons make them suitable for the transmission of nerve impulse? (e.g. how does the structure of neurons dictate the function of neurons)
Dendrites (short extensions) receive impulses from other axons. Axons (long extensions) carry electrical impulses away from cell to other neurons.
Identify the four types of tissue in the body, and describe the major functions of each tissue.
Epithelial tissue - layers of cells that cover the surfaces of the body (e.g. internal cavity linings, glands, surfaces exposed to outside exterior). Connective tissue - binds the cells and organs of the body together (e.g. protection, support, and integration) Muscle tissue - 3 types: skeletal, smooth, cardiac. All respond to stimulation and provide movement. Nervous tissue - transmit info and receive signals throughout body
In observing epithelial cells under a microscope, the cells are arranged in a single layer and look tall and narrow, and the nucleus is located close to the basal side of the cell. The specimen is what type of epithelial tissue? a. columnar b. stratified c. squamous d. transitional
a. columnar
The process by which a less specialized cell matures into a more specialized cell is called ________. a. differentiation b. maturation c. modification d. specialization
a. differentiation
The cells of muscles, myocytes, develop from ________. a. myoblasts b. endoderm c. fibrocytes d. chondrocytes
a. myoblasts
Connective tissue is made of which three essential components? a. cells, ground substance, and carbohydrate fibers b. cells, ground substance, and protein fibers c. collagen, ground substance, and protein fibers d. matrix, ground substance, and fluid
b. cells, ground substance, and protein fibers
Which of the following is not a type of tissue? a. muscle b. nervous c. embryonic d. epithelial
c. embryonic
What is the function of synovial membranes?
Allows joints to move freely by serving as a natural lubricant in the joint cavity. Aids mobility.
