A&P exam 1 ch.5

. The ________ exocrine gland stores its secretion until the glandular cell ruptures, whereas the ________ gland releases its apical region and reforms. holocrine; apocrine eccrine; endocrine apocrine; holocrine eccrine; apocrine

Holocrine; apocrine

epithelial tissue

Sheets of tightly packed cells that line organs and body cavities

The structure of a tissue usually is optimized for its function. Describe how the structure of the mucosa and its cells match its function of nutrient absorption.

The mucosa of the intestine is highly folded, increasing the surface area for nutrient absorption. A greater surface area allows more nutrients to be absorbed per unit time.

adipose tissue

Tissue that stores fat, reduces heat loss, energy reservoir, supports and protects and is found around areolar tissue.

. Which connective tissue specializes in storage of fat? tendon adipose tissue reticular tissue dense connective tissue

adipose tissue

Which of the following central nervous system cells regulate ions, regulate the uptake and/or breakdown of some neurotransmitters, and contribute to the formation of the blood-brain barrier? microglia neuroglia oligodendrocytes astrocytes

astrocytes

The nerve impulse travels down a(n) ________, away from the cell body. dendrite axon microglia collagen fiber

axon

what are the three types of muscle tissue?

cardiac, smooth, skeletal

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? columnar stratified squamous transitional

columnar (?)

Why does skeletal muscle look striated?

due to the arrangement of the contractile proteins actin and myosin.

connective tissue matrix is..

fluid, semisolid, gelatinous, fibrous, calcified, and is secreted by connective tissue cells and adjacent cells

Under the microscope, a tissue specimen shows cells located in spaces scattered in a transparent background. This is probably ________. loose connective tissue a tendon bone hyaline cartilage

hyaline cartilage

what does smooth muscle look like?

in blood vessels, and involuntary

classification of exocrine glands

merocrine glands apocrine glands holocrine glands

Skeletal muscle is composed of very hard working cells. Which organelles do you expect to find in abundance in skeletal muscle cell? nuclei striations golgi bodies mitochondria

mitochondria

. Which of the following lines the body cavities exposed to the external environment? mesothelium lamina propria mesenteries mucosa

mucosa

what type of tissue is bone? what is ti made up of?

osseous tissue. matrix w/ salts and fibers,

. In bone, the main cells are ________. fibroblasts chondrocytes lymphocytes osteocytes

osteocytes

What are the functions of astrocytes?

physical and metabolic support for neurons, detoxification, guidance during migration, regulation of energy metabolism, electrical insulation (for unmyelinated axons), transport of blood-borne material to the neuron, and reaction to injury.

Blood is made up of

plasma(matrix) , red blood cells, white blood cells, platelets, formed elements=cells

list the classification of epithelial tissue

shapes: squamous, cuboidal, columnar, transitional, layers: simple, stratifies, pseudostratified

. Which of the following is the epithelial tissue that lines the interior of blood vessels? columnar pseudostratified simple squamous transitional

simple squamous

what does cardiac muscle look like?

striated, branching, and involuntary

what does skeletal muscle look like?

striated, multi-nucleated (eccentric), fibers parallel
