Exam 1: Introduction to Physiology and Homeostasis

Secretion refers to the release from a cell, in response to appropriate stimulation, of specific products that have in large part been synthesized by the cell.

Temperature-sensitive nerve cells monitor the body temperature and provide information about its status to a temperature-control center in the hypothalamus, a part of the brain. The hypothalamus can bring about adjustments in body temperature by inducing shivering or sweating, among other things. Indicate the roles served by each component of this control system using the following answer code: -hypothalamus

Not all activities performed by the muscular and nervous systems are directed toward maintaining homeostasis.

Glands are formed during embryonic development by pockets of epithelial tissue that dip inward from the surface.

____________________ muscle tissue composes the heart.

On the image four major components of a homeostatic system are labeled A, B, C and D. Match the components with the statements below. Answers can be used more than once. All of the statements are in reference to temperature regulation. -Part of the nervous system that signals sweat glands to produce sweat.

Calcium is stored mainly in the ____ system.

____________________ refers to the abnormal functioning of the body associated with disease.

Exocrine glands are the only structures in the body capable of secretion.

MATCHING Use the following answer code to indicate which tissue is being identified. -This tissue is distinguished by relatively few cells within an extracellular material.

Compare negative and positive feedback and explain why negative feedback is important in homeostasis.
