Question
15 Nervous System TRUE OR FALSE (1 pt. ea.) (The key word or phrase for each is in bold print.) In the central nervous system, the gray matter is always peripheral to the white matter. 2. In a spinal nerve, motor neurons are the only neurons bringing impulses towards the spinal cord. 3.--The most posterior lobe of the cerebrum is the parietal lobe. 4. The involuntary, efferent neurons connecting to the smooth muscles of the viscera are of the autonomic nervous system. 5. The autonomic neurons of the cranial and sacral peripheral nerves are of the parasympathetic nervous system. 6. The meninges are protective membranes surrounding the central nervous system. 7. The thalamus is not part of the brain. 8. 9. The surface layer of the cerebrum is called the cerebral cortex. The cerebellum is responsible for coordinating interactions between all higher regions of the brain.Explanation / Answer
1. In the central nervous system the gray matter is always peripheral to the white matter is True because white matter contains relatively few cell bodies and is composed chiefly of long-range myelinated axon tracts.
2. In a spinal nerve the motor neurons are the only neurons bringing impules towards the spinal cord the statement is False because the sensory nerves bringing the impules towards the spinal cord not the motor nerves.
3. The most posterior lobe of the cerebrum is the pariental lobe the statement is False
4. The involuntary effernet neurons are connecting to the smoth muscle of viscera are of the autonomic nervious system the statement is True Because Autonomic nervous system is a subdivision of the peripheral nervous system which controls involuntary activity of visceral muscles and internal organs and glands.
5. The Autonomic neurons of the cranial and saceral peripheral nerves are of the parasympathetic nervious system the statement is True.
6. The meninges are protective membranes surrounding the central nervious system the statement is true.
7. The thalamus is not part of the brain the statement is false because the thalamus is present in the brains and secretes the various hormones.
8. The surface layer of the cerebrum is called the cerebral cortex the statement is True.
9. The cerebellum is responsible for coordinating intraction between all higher regions of the brain the statement is true.
