b) Describe the autonomic nervous system.
Question 2 (1.3) 100 words
Using Illustrations, and a short commentary, describe the sensory and motor neuron.
Question 3 (1.3) 150 words
Explain, using illustrations, the function of a motor neuron and a sensory neuron in a reflex arc using the example of a knee jerk (patellar) reflex.
Question 4 (2.1, 2.3) 350 words
Describe and explain the transmission of an action potential in a myelinated neurone. Explain the importance of the myelin sheath and the refractory period in determining the speed of nervous impulses.
Question 5 (2.2) 100 words
Describe the all-or-nothing nature of nerve impulses.
Question 6 (3.1) 300 words
Describe the structure of a cholinergic synapse, and explain how it functions.
Question 7 (3.2) 200 words
The illustration below explains the role of synapses. Explain the role of the synapse in the nervous system in determining the direction of nerve impulse transmission, allowing the interconnection of nerve pathways.

Paraphrase citation
Use the citation to the endpoint in each response
stick to OpenStax and Lumen Learning, or A-Level Biology textbooks
Try to give additional specific facts and details like numerical information, specific cellular/histological details.
Reduced the surrounding wording or opening sentences to instead directly describe or explain versus the question/AC instructions.
