Homeostatic Control Mechanisms and Senses

What are the three main components of homeostatic control mechanisms?

Describe the role of receptors in homeostatic control mechanisms.

Identify one positive and one negative feedback mechanism in homeostasis.

What types of receptors are taste and smell classified as?

List the four basic tastes recognized and the additional one considered a fifth taste.

Homeostatic Control Mechanisms

Homeostatic control mechanisms monitor the internal environment and correct variations that are outside of limit.
It has three parts:
- Receptor: provides information about stimuli
- Control Center: tells what the set point should be
- Effector: elicits responses to change internal environment conditions
Two types of mechanisms:
- Negative feedback mechanisms
- Positive feedback mechanisms

Special Sensory Receptors

Receptors are not free nerve endings of sensory neurons.
They are specialized receptor cells.
They are localized in the head region.
These receptors include taste, smell, sight, hearing, and balance.

Taste (Gustation)

Taste, or gustation, is mediated by taste buds in taste papillae on the tongue.
Taste buds have a standardized pattern.
Taste receptors occur in taste buds.
Most taste receptors are located on the surface of the tongue in the papillae.
Four basic tastes: sweet, sour, salty, and bitter
A fifth taste, umami, is perceived as "deliciousness"
There is no structural difference among taste buds.
Taste receptors are chemoreceptors which respond to chemicals.

Explore the fascinating concepts of homeostatic control mechanisms and special sensory receptors. This quiz covers the roles of receptors, control centers, and effectors in maintaining internal balance, as well as the structure and function of taste and other specialized senses.
