1. which part of the nervous system is responsible for basic functions like breathing?

a. peripheral nervous system
b. central nervous system
c. somatic nervous system
d. autonomic nervous system

Explanation:

1. Neurons are the basic units of the nervous system and their main role is to transmit messages (electrical and chemical signals) throughout the body.
2. The synaptic gap (synaptic cleft) is the small space between the axon terminal of one neuron and the dendrite or cell body of another neuron - it's the contact point for signal transmission.
3. Neurotransmitters are chemicals that neurons use to communicate with each other across the synaptic gap.
4. The pituitary gland is often called the "master gland" because it controls the functions of many other endocrine glands by secreting hormones that regulate them.
5. Adrenaline (epinephrine) is released during the fight - or - flight response, which prepares the body for action in a stressful situation.
6. The central nervous system (brain and spinal cord) is responsible for basic functions like breathing, as it controls many involuntary processes.

Answer:

1. B. Transmitting messages
2. B. The contact point between two neurons
3. B. Chemicals that transmit signals between neurons
4. C. Pituitary gland
5. C. Adrenaline
6. B. Central Nervous System
