The nervous system is produced during embryonic development through a process called neurulation. The neural tube forms from the ectoderm layer of the embryo and gives rise to the brain and spinal cord, while neural crest cells migrate to form peripheral nerves and contribute to other structures in the body.

Is the adrenal cortex an extension of the sympathetic nervous system?
No, the adrenal cortex is not an extension of the sympathetic nervous system. The adrenal cortex is the outer region of the adrenal gland that produces hormones like cortisol and aldosterone. The sympathetic nervous system is a part of the autonomic nervous system that controls the body's fight or flight response.
Which type of cell produces the myelin covering around the axon of a neuron?
Oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system produce the myelin sheath that covers axons of neurons.
What organ of the endocrine system also interacts with the nervous system?
The adrenal gland is an organ of the endocrine system that interacts with the nervous system. It is responsible for producing hormones such as adrenaline in response to stress, which can trigger a fight-or-flight response mediated by the nervous system.
Does the central nervous system consist of the somatic nervous system?
No, the central nervous system consists of the brain and spinal cord. The somatic nervous system is a division of the peripheral nervous system that controls voluntary movements and receives sensory information.
The portion of the nervous system away from the central nervous system?
The peripheral nervous system is the portion of the nervous system away from the central nervous system. It consists of nerves that connect the central nervous system to the rest of the body, including sensory and motor neurons. The peripheral nervous system is responsible for transmitting information to and from the central nervous system.
What part of nervous system produces some behaviors on its own?
The autonomic nervous system produces behavior on its own.
Which part of the brain sends impulses to the nervous system in time of emergency?
The emergency, or "fight or flight" part of the nervous system is the sympathetic nervous system. The parasympathetic nervous system produces a "rest and digest" response.
What part of body produces endorphins?
The nervous system, especially the brain, produces endorphins.
How do humans get nervous?
People become nervous because their sympathetic nervous system produces too much adrenaline.
Classification of drug that depresses the central nervous system and usually produces sleep?
the classification of a drug that depresses the central nervous system and usually produces sleep is known as a hypnotic.
Is the adrenal cortex an extension of the sympathetic nervous system?
No, the adrenal cortex is not an extension of the sympathetic nervous system. The adrenal cortex is the outer region of the adrenal gland that produces hormones like cortisol and aldosterone. The sympathetic nervous system is a part of the autonomic nervous system that controls the body's fight or flight response.
What organ of the endocrine system also interact with the nervous system?
the nervous system and the endocrine system are joined together by the HYPOTHALAMUS. The HYPOTHALAMUS is part of the central nervous system(CNS).I receives,sorts, and interprets signals from neurons. It is also part of the endocrine system and produces hormones. -JMAR14
How does the brain help the nervous system?
The brain is the most important and central organ of the entire nervous system. It receives sensory input (afferent feedback) from the rest of the nervous system, processes information, and produces efferent signals and responses to the rest of the nervous system. Analogous to a computer system, the brain would be the central processing unit.
The classification of drug that depresses the central nervous system and usually produces sleep is known as?
hypnotic
Which type of cell produces the myelin covering around the axon of a neuron?
Oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system produce the myelin sheath that covers axons of neurons.

The adrenal gland is an organ of the endocrine system that interacts with the nervous system. It is responsible for producing hormones such as adrenaline in response to stress, which can trigger a fight-or-flight response mediated by the nervous system.
The effects of the sympathetic nervous system are essentially opposite of which nervous system?
The effects of the sympathetic nervous system are essential opposite those of the parasympathetic nervous system. The sympathetic nervous system accelerates functions such as heart rate and breathing and the parasympathetic slows these bodily processes down. The sympathetic also inhibits digestion, whereas the parasympathetic stimulates digestion. The sympathetic nervous system produces "fight-or-flight" reactions, while the parasympathetic functions under relaxed conditions.
