This assignment is designed to get you thinking about the functions of some of the structures in the central and peripheral nervous system. Listed below are different symptoms or complications that can be attributed to something from the nervous system. List the specific structure that is most likely the root cause of the pathology. In addition, label which branch of the nervous system that structure is a part of (CNS or PNS). I suggest making a table with the pathology in one column, the affected structure in the next column, and the nervous system section in the final column. Two examples are below. It is possible that more than one answer could be correct. Pathology/Patient Specific Structure CNS or PNS? John’s eyes and optic nerve are in optimal condition, but he is still classified as legally blind. Primary Visual Cortex CNS Although Meredith is the CEO of Yankee Candle, she cannot smell a thing. She has no history of allergies and tested negative for COVID.…

Please answer all of the following questions in your own words, thank you: this assignment is on the nervous system and nervous tissue. Q1: Explain the differences between different types of graded potentials? Also, Categorize 4 major neurotransmitters by chemical type and effect? Q2:
1. Label the parts of this neuron: 2. Explain the function of each component in #1. 3. Mark the following statements as TRUE or FALSE: An action potential is something that only occurs at synapses. Afferent pathways send sensory information to the CNS for processing. When they are at rest, neurons are more positively charged inside than outside the cell. FALSE Action potentials originate at the axon terminal and move towards the dendrites. An action potential travels down the length of the neuron with the help of voltage-gated calcium channels. Neurons can only have one action potential and must be recycled by glia once they have depolarized. At axon terminals, calcium influx stimulates vesicle release. Ligand-gated ion channels open in response to a molecule binding to them. 4. For each FALSE statement in #3, explain why it is incorrect.

Classify the following characteristics to demonstrate your knowledge of differences between the autonomic and somatic divisions of the nervous system. Neurons release acetylcholine that binds to nicotinic acetylcholine receptors located on the effector organs Can lead to excitation or inhibition of the Neurons are also called motor neurons effectors Receptors on effector organs are also responsive to epinephrine that is released into the blood by the adrenal medulla Innervates smooth and cardiac muscle, glands, and Gl neurons Neurons release norepinephrine that binds to adrenergic receptors located on the effector organs Has two-neuron chain between the CNS Single neuron between the CNS and effectors Neurons release acetylcholine that binds to muscarinic acetylcholine receptors located on the effector organs and effectors Can lead only to excitation of the effectors Activates skeletal muscles Autonomic Nervous System Somatic Nervous System
Neurofibromatosis type 1 is a condition where tumours can grow in the nerves near the skin. The growth of tumours prevents the action potentials from quickly travelling through the neurons. Identify the nerve structure from the image below and the division of the nervous system affected by neurofibromatosis type 1. CNS = Central Nervous System PNS = Peripheral Nervous System Select one: a. Nerve Structure Division of Nervous System 3 PNS b. Nerve Structure Division of Nervous System 4 CNS c. Nerve Structure Division of Nervous System 5 PNS d. Nerve Structure Division of Nervous System 1 CNS
