Question

question 1
(q001) after learning about neurons, mariah looks at her cell phone and thinks about how it receives signals from the local cell tower. she realizes that there are antennas in her phone that receive radio signals from cell towers, and that these antennas are similar to ______, which are the parts of the neurons that receive incoming messages.
a. cell bodies
b. myelin sheaths
c. synaptic vesicles
d. dendrites

question 2
(q002) when jameson gets a foot massage, the neurons in his feet send messages to ______, which in turn generate action potentials that are sent down the length of the neurons to other cells.
a. synaptic clefts
b. axon terminals
c. cell bodies
d. synaptic clefts

question 3
(q003) the smallest units of communication in the nervous system, the cells that are responsible for all of your thoughts and behaviors, are called ______.
a. neurons
b. neurotransmitters
c. oligodendrocytes
d. schwann cells

question 4
(q004) ming is figuring out the best way to sequence the various tasks he has to complete today. what part of mings brain is most involved in organization, planning, and complex thinking?
a. association cortex
b. ventral tegmental cortex
c. primary somatosensory cortex
d. prefrontal cortex

Explanation:

• Question 1: Dendrites are the parts of neurons that receive incoming messages, similar to how phone antennas receive signals.
• Question 2: When neurons in the feet send messages, they send them to the cell bodies which generate action - potentials.
• Question 3: Neurons are the smallest units of communication in the nervous system responsible for thoughts and behaviors.
• Question 4: The prefrontal cortex is involved in organization, planning, and complex thinking.

Answer:

• Question 1: d. dendrites
• Question 2: c. cell bodies
• Question 3: a. neurons
• Question 4: d. prefrontal cortex
