Homeostasis and regulatory systems

When you are hot, your body sweats to cool you down. This means your temperature went above normal and your body sweats to counteract that change to bring you back to normal. What kind of feedback loop would this be?

• Negative Feedback Loop

• Positive Feedback Loop

• Neutral Feedback Loop

• Opposite Feedback Loop

The junction between neurons is termed a:

• synaptic knob.

• synaptic cleft.

• synapse.

• neurotransmitter.

Sensory (afferent) neurons are those that:

• Receive a stimuli and carry information from a receptor to the CNS

• Transmit information from the central nervous system to an effector organ to bring about a response

• Relay information between sensory input and motor output

• Act as a link between neurons

Homeostasis is maintained by:

• neutral feedback loops

• solar feedback loops

• positive feedback loops

• negative feedback loops
