Full Question:
The spinal cord and brain include regions called "nuclei." These are areas where synapses generally occur and consist of:
A) Oligodendrocytes
B) Axons of Spinal and Cranial Nerves
C) Cluster of Neuronal Cell bodies
D) Schwann Cell
E) Ganglia
Answer:
The correct answer is C)
The Nuclei consists of a cluster of Neuronal Cell Bodies.
Explanation:
The study of the anatomy of the nervous system shows that the nuclei (which is the plural form of nucleus) is a cluster of neurons in the central nervous system located deep within the cerebral hemispheres and the brainstem.
Tracts, bundles (fascicles) of nerve fibers (also called axons) protruding from the body of the cell help connect nuclei to other nuclei.

Individuals who are high users of pain-relieving medications are <u>less likely</u> to benefit from pain management programs than less frequent users.
Pain occurs when there is a disease condition, Analgesics are the painkillers drugs used to relieve the pain in the body. These medications are taken for all types of pain like- injury, internal pain of the body, headache, etc., Individuals who take a high dose of pain killers get addicted to them. In such individuals, there is no effect of the painkillers and the pain becomes severe. This is why they are less likely beneficial from Pain Management Program.

Answer:
Positive feedback
Explanation:
The homeostasis of the body is generally maintained by the feedback mechanism of the body. Two main types of feedback mechanism are positive feedback and negative feedback mechanism.
Positive feedback mechanism may be defined as in which the final product of the reaction or hormone increase the further secretion of that particular hormone. The positive feedback mechanism can exaggerates the effect of the variation from the normal condition of the body.
Thus, the correct answer is option (e).
Answer:
The correct answer will be option-D.
Explanation:
Conduction system of the heart contains autorhythmic fibres which are usually Nodes of the heart. There are two types of nodes-Sinoatrial node and the atrioventricular node.
The sinoatrial node is known as the pacemaker of the heart as it maintains the pace of the heartbeat due to its efficiency if higher depolarization than other node and conduction cells like a bundle of His and Purkinje fibres.
Since depolarization causes a contraction in the muscle cells, therefore, heartbeats and thus option-D is the correct answer.
