Anatomy and Physiology- Tissues Questions
and Answers
Tissues - ✅✅Groups of cells that are similar in structure and function
Nervous Tissue - ✅✅responsible for internal communication; neurons and neuroglia; contains brain,
spinal cord, and nerves
Muscle Tissue - ✅✅A body tissue that contracts or shortens, making body parts move; has cardiac,
skeletal, and smooth muscles
Epithelial Tissue - ✅✅Tissue that forms boundaries between different environments, protects,
secretes, absorbs, and filters; located in glands, skin surface, and lining of hollow organs
Connective Tissue - ✅✅supports, protects, binds other tissues together; locations can be bones,
tendons, and fat/padding tissue
Epithelial tissue types - ✅✅a. simple squamous epithelium
b. simple cuboidal epithelium
c. simple columnar epithelium
d. stratified squamous epithelium
e. stratified cuboidal epithelium
f. stratified columnar epithelium
g. transitional epithelium
h. pseudostratified epithelium
i. glandular epithelium
simple squamous epithelium (description) - ✅✅single layer of flattened cells with disc-shaped central
nuclei and sparse cytoplasm; the simplest of the epithelia
, simple squamous epithelium (function) - ✅✅allows materials to pass by diffusion and filtration in
sites where protection is not important; secretes lubricating substances in serosae
simple squamous epithelium (locations) - ✅✅Kidney glomeruli; air sacs of the lungs; lining of heart,
blood vessels and lymphatic vessels; lining of ventral body cavity (serosae)
simple cuboidal epithelium (description) - ✅✅single layer of cubelike cells with large, spherical
central nuclei
simple cuboidal epithelium (function) - ✅✅secretion and absorption
simple cuboidal epithelium (locations) - ✅✅Kidney tubules; ducts and secretory portions of small
glands; ovary surface
simple columnar epithelium (description) - ✅✅single layer of tall cells with round to oval nuclei; some
cells bear cilia; layer may contain mucus-secreting unicellular glands (goblet cells)
simple columnar epithelium (function) - ✅✅absorption; secretion of mucus, enzymes, and other
substances; ciliated type propels mucus (or reproductive cells) by ciliary action
simple columnar epithelium (locations) - ✅✅Lining of stomach, intestine, gallbladder, uterine tubes,
and collecting ducts of kidneys
pseudostratified columnar epithelium (description) - ✅✅single layer of cells of differing heights, some
not reaching the free surface; nuclei seen at different levels; may contain mucus-secreting cells and bear
cilia
pseudostratified columnar epithelium (function) - ✅✅secrete substances, particularly mucus;
propulsion of mucus by ciliary action
pseudostratified columnar epithelium (location) - ✅✅nonciliated type in male's sperm-carrying ducts
and ducts of large glands; ciliated variety lines the trachea, most of the upper respiratory tract
