Human Anatomy - Head and Neck Worksheet 4
In the adenohypophysis, the pars tuberalis, which wraps around the adjacent portion of the infundibulum, represents the major portion of the pituitary gland. True False
False
The parafollicular cells of the thyroid produce the hormone calcitriol. True False
False
What is the mechanism of calcitonin's function(s), the hormone that is produced by C thyrocytes? It stimulates osteoblasts and osteoclasts. It increases the rate of cellular metabolism and oxygen consumption in almost every cell in the body. It inhibits osteoclasts and stimulates calcium ion excretion at the kidneys. It decreases the rate of cellular metabolism and oxygen consumption in almost every cell in the body. It promotes the development and maturation of lymphocytes.
It inhibits osteoclasts and stimulates calcium ion excretion at the kidneys.
What is the location of the lacrimal gland? It extends along the nasolacrimal canal formed by the lacrimal bone and the maxilla. It nestles within a depression in the frontal bone, within the orbit and superior and lateral to the eyeball. It is located in the area of the medial canthus. It is nestled within the ethmoid bone, medial to the superior orbital fissure. It runs along grooves in the surface of the lacrimal bone.
It nestles within a depression in the frontal bone, within the orbit and superior and lateral to the eyeball.
The chemoreceptors of carotid bodies trigger reflexive adjustments in respiratory and cardiovascular activity via which cranial nerve? N IX N VII N XI N V N X
N IX
Melanocyte-stimulating hormone, the only hormone released by the pars intermedia, is secreted by corticotropes only during fetal development, in young children, in pregnant women, and in some disease states. True False
True
The neurohypophysis of the pituitary gland contains the axons and axon terminals of roughly 50,000 hypothalamic neurons whose cell bodies are either in the supraoptic or paraventricular nuclei. True False
True
The types of cells found in the parathyroid gland are the parathyroid cells (productive glandular cells) and the oxyphil cells and transitional cells, which are probably immature or inactive forms of the parathyroid cells. True False
True
Parathyroid hormone stimulates the production of which hormone(s)? calcitriol thymosins thyroxine calcitonin triiodothyronine
calcitriol
