Nervous System Flashcards
What are the three sections of the brain?
- Cerebrum
- Cerebellum
- Brain stem
The cerebrum is made up of 5 lobes - what are they?
- the frontal lobes
- the parietal lobes
- the temporal lobes
- the insular lobe
- the occipital lobes
What is the function of the frontal lobes?
voluntary movement, expressive language and for managing higher-level executive functions
What is the function of the parietal lobes?
sensory perception and integration, including the management of taste, hearing, sight, touch and smell
What is the function of the temporal lobes?
processing auditory information and the encoding of memory
What is the function of the insular lobe?
consciousness and the regulation of the body’s homeostasis
What is the function of the occipital lobes?
the brain’s visual cortex, allowing you to see and process stimuli from the external world and to assign meaning to and remember visual perceptions
What is the cerebellum responsible for?
- Maintenance of balance and posture
- Coordination of voluntary movements
- Motor learning
- Cognitive functions
What three sections is the brainstem composed of?
- Midbrain
- Pons
- Medulla oblongata
What are the 12 cranial nerves, in order? (not functions)
- Olfactory nerve
- Optic nerve
- Oculomotor nerve
- Trochlear nerve
- Trigeminal nerve
- Abducens nerve
- Facial nerve
- Auditory/vestibular nerve
- Glossopharyngeal nerve
- Vagus nerve
- Accessory nerve
- Hypoglossal nerve
What is the function of the olfactory nerve?
Sense of smell
What is the function of the optic nerve?
Ability to see
What is the function of the oculomotor nerve?
Ability to move and blink your eyes
What is the function of the trochlear nerve?
Ability to move your eyes up and down or back and forth
What is the function of the trigeminal nerve?
Sensations in your face and cheeks, taste and jaw movements
