Unit 3.04 Sensory

Maintaining body temperature is an example of a:

• negative feedback loop
• positive feedback loop

When glucose levels in the blood rise, your brain sends a signal to your pancreas. The pancreas releases insulin, which opens channels in cell membranes to allow glucose to enter the cell, lowering blood sugar levels. 

• Positive Feedback Response
• Negative Feedback Loop 

Which of the TWO nervous systems contains motor and sensory neurons?

• central nervous system
• peripheral
• motor
• sensory

The "cause" for something to happen is the

• response
• effect
• stimulus
• homeostasis

What kind of messages does the nervous system send?

• magical
• chemical (hormones)
• electrical (impulses)
• telegrams

Which part of the neuron is a long fiber that send information to other cells?

• dendrite
• terminal
• cell body
• axon

Failure to maintain homeostasis could result in:

• lack of internal balance
• eventual death
• difficulty carrying on metabolism 
• all three

What are specialized nerve endings that detect change inside and outside the body?

• interneurons
• receptors
• motor neurons
• reflex arc

The function of dendrites is to:

• Receive information from other neurons

• Secrete neurotransmitters to the postsynaptic neuron

• Provide energy for the synthesis of acetylcholine

• Connect the cell body with the terminal branches

• Speed up transmission of synaptic neurotransmitters

To toss a salad, use a:

• spoon to thoroughly mix ingredients with a circular, up and down motion.

• rubber spatula to gently blend heavy and delicate mixture

• sieve to mix ingredients

• set of tongs to gently tumble together ingredients
