Question 1. Match the labelled synapse structure with the correct structure or function. Place the correct number in each blank. Use each answer only once.

receptor site for the neurotransmitter (dendrite)

neurotransmitter released by exocytosis from a vesicle

neurotransmitter; the chemical messenger

acetylcholinesterase; an enzyme that breaks down ACh (Acetylcholine)

synaptic vesicle containing the neurotransmitter ACh (Acetylcholine)

axon terminal; the axon knob

synpatic cleft; the synapse; a gap

postsynaptic membrane; of the dendrite; "after" the synapse

presynaptic membrane; of the axon; "before" the synapse

mitochondria; supply ATP for synthesis of transmitters

Structure I

i attached the first picture for matching, the second picture is there to help to solve question 1


i had done question 2, but im stuck on the matching i will put down what i matched and tell me if im wrong and give me the right matching for it because i haven't done 2 of them which is parietal lobe and temporal lobe i cant match them.


Question 2.

5. cerebrum

6. frontal lobe

4. medulla oblongata

7. cerebellum

10.corpus callosum

8.thalamus

3. occipital lobe

parietal lobe

temporal lobe

9.hypothalamus


1.   
relay centre; directs impulses from the senses to the correct brain region

2.   
of the cerebrum; auditory interpretation; impulses are from the organ Corti

3.   
of the cerebrum; visual interpretation; impulses are from rods and cones

4.   
involuntary control of heart rate, breathing rate, blood pressure, and swallowing

5.   
conscious control; thinking, creative thought, emotions, interpretation of sense receptor impulses (eyes, ears, skin)

6.   
of the cerebrum; conscious thought; intelligence, memory, personality; controls voluntary motor-muscle action (such as to throw a ball)

7.   
unconscious control of muscle co-ordination and balance

8.   
sends messages from one cerebral hemisphere to the other; connects right and left hemispheres

9.   
direct link to the pituitary gland of the endocrine system; has a major role in homeostasis regulating HR, BR, temperature, and drives (hunger, thirst, rage, and sexual desires)

10.   
of the cerebrum; taste; sense receptors from the body/skin are interpreted (such as Tabasco sauce on the lips)

sorry about that, i see that you chose F twice for receptor site for the neurotransmitter (dendrite) and axon terminal; the axon knob. A isnt chosen so is axon terminal; the axon knob A or F? or vise versa

Thank you for your help!

The bottom F should be an A.

Thank you

Were the answers correct? Please update us.

Thank you so much!

Saved my life.

THANKS!

Thank you so much!! :)

THANK YOUU!

thanks a lot :)

Thanks! This question drove me nuts for a while.

Thanks!

I had my 12 year old sister trying to help me and then my mom, the diagram is a little crazy! thank you so much

thank you

Thank you
