NSG 207 Exam 4
1. CNS (central nervous system):
Answer brain and spinal cord
2. Meninges:
Answer covers the CNS protects and nourishes
3. Subarchnoid space:
Answer surrounds brain and spinal cord, filled with cerebrovascular fluid, cushions brain and spinal cords, nourishes CNS, removes waste products
4. Cerebrospinal fluid (CSF):
Answer Fluid produced in the ventricles of the brain that flows in the subarachnoid space and bathes the meninges.
5. Neurons:
Answer govern electrical activity throughout sensory and motor neural path- ways
6. Upper motor neurons:
Answer motor neurons in the central nervous system that control the lower motor neurons in the peripheral nervous system
- The brain is composed of four major regions::
Answer
- Cerebrum
- Diencephalon
- Brainstem
- Cerebellum
SUBSCRIBE
8. Four lobes of the cerebrum:
Answer frontal temporal parietal occipital
9. Frontal lobe function:
Answer directs voluntary, skeletal actions, communication, emotions, intellect, judgment
10. Temporal lobe function:
Answer auditory, wernickle is here
11. Occipital lobe function:
Answer visual processing
12. Parietal lobe function:
Answer tactile sensations
13. Diencephalon:
Answer thalamus and hypothalamus
- Diencephalon: Thalamus:
Answer relay and processing centers for sensory information
- Diencephalon: Hypothalamus:
SUBSCRIBE
Answer centers controlling emotions, autonomic functions, and hormone production
16. Brain stem consists of:
Answer midbrain, pons, medulla oblongata
- Brain Stem: Midbrain:
Answer tracks visual stimuli and reflexes triggered by sound
- Brain Stem: Pons:
Answer Your pons is a part of your brainstem, a structure that links your brain to your spinal cord. It handles unconscious processes and jobs, such as your sleep-wake cycle and breathing. It also contains several junction points for nerves that control muscles and carry information from senses in your head and face.
- Brain Stem: Medulla Oblongata:
Answer The medulla oblongata contains cardiac, respiratory, vomiting, and vasomotor centers.It deals with the autonomic functions of breathing, heart rate, blood pressure, and sleep- wake cycle.
20. Cerebellum:
Answer Balance and coordination
21. Spinal cord:
Answer located in the vertebral canal extends from medulla obligation to the first lumbar vertebra consists of two pairs of columns (dorsal, ventral) conducts nerve impulses
SUBSCRIBE
22. Spinal cord white and gray matter:
Answer white matter outside, gray matter inside
23. Afferent nerves (sensory nerves):
Answer nerves that carry information about the external environment to the brain and spinal cord via sensory receptors
24. Efferent nerves (motor nerves):
Answer nerves that carry information out of the brain and spinal cord to other areas of the body
25. Peripheral Nervous System (PNS):
Answer the sensory and motor neurons that connect the central nervous system (CNS) to the rest of the body consists of 12 pairs of cranial nerves
26. 12 cranial nerves in order mnemonic:
Answer
- Olfactory (s)
- Optic (s)
- Oculomotor (m)
- Trochlear (m)
- Trigeminal (b)
- Abducens (m)
- Facial (b)
- Vestibulocochlear (s)
- Glossopharyngeal (b)
- Vagus (b)
- Accessory (m)
- Hypoglossal (m)
