corpusculeB) Tactile CorpuscleC) Ruffini bodyD) free nerve ending.
Answer: B
◍ stratified epithelial tissue.
Answer: more layers
◍ epithelial tissues are classified according to.
Answer: number of layers and cell shape
◍ simple squamos epithelium function.
Answer: allows materials to pass by diffusion and filtration in sites where
protection is not important; secretes lubricating substances in serosae
◍ simple squamous epithelium location.
Answer: Kidney glomeruli; air sacs of the lungs; lining of heart, blood
vessels and lymphatic vessels; lining of ventral body cavity (serosae)
◍ Which glands produce ear wax?A) merocrine glandsB) apocrine glandsC)
ceruminous glandsD) eccrine glands.
Answer: C
◍ simple cuboidal epithelium function.
Answer: secretion and absorption
◍ Which type of skin cancer appears as a scaly reddened papule and tends to
grow rapidly and metastasize?A) melanomaB) squamous cell carcinomaC)
basal cell carcinomaD) adenoma.
Answer: B
◍ Melanocytes and keratinocytes work together in protecting the skin from
, UV damage when Keritonocytes _____________.A) provide the
melanocyte with nutrients necessary for melanin synthesisB) accumulate the
melanin granules on their superficial portion, forming a UV-blocking
pigment layerC) maintain the appropriate pH in order for the melanocyte to
synthesize melanin granulesD) maintain the appropriate temperature so the
product of the melanocyte will not denature.
Answer: B
◍ simple cuboidal epithelium location.
Answer: Kidney tubules; ducts and secretory portions of small glands; ovary
surface
◍ simple columnar epithelium function.
Answer: absorption; secretion of mucus, enzymes, and other substances;
ciliated type propels mucus (or reproductive cells) by ciliary action
◍ simple columnar epithelium location.
Answer: Nonciliated type lines most of the digestive tract (stomach to
rectum), gallbladder, and excretory ducts of some glands; ciliated variety
lines small bronchi, uterine tubes, and some regions of the uterus.
◍ pseudostratified columnar epithelium function.
Answer: secrete substances, particularly mucus; propulsion of mucus by
ciliary action
◍ pseudostratified columnar epithelium location.
Answer: nonciliated type in male's sperm-carrying ducts and ducts of large
glands; ciliated variety lines the trachea, most of the upper respiratory tract
◍ The dermis is a strong, flexible connective tissue layer. Which of the
following cell types are likely to be found in the dermis?A) goblet cells,
parietal cells, and chondrocytesB) monocytes, reticulocytes, and
osteocytesC) fibroblasts, macrophages, and mast cellsD) osteoblasts,
osteoclasts, and epithelial cells.
Answer: C
