What are the 6 main functions of the nervous system?
|
1. Rapid Communication
2. Sensory input 3. Integration of sensory input into homeostatic control and decisions 4. Motor output 5. Reflexes 6. Higher brain functions, homeostasis, integration and coordination with other systems (endocrine, muscular, etc.) |
|
What are the 2 parts to the CNS?
|
Brain, spinal cord
|
|
What are the 2 divisions of the PNS?
|
Sensory (affect)
Motor (effect) |
|
What is a way to remember affect vs effect?
|
affect literally means to influence, sensing something will influence an effect (doing something, like a motor action)
|
|
What are the 2 subdivisions within sensory and motor?
|
Visceral and somatic
|
|
Which division contains sympathetic and parasympathetic subdivisions?
|
Visceral motor
[PNS->Motor Division->Visceral motor] |
|
Sensory neurons do what and are part of which division of the nervous system?
|
PNS; conduct signals from receptors to the CNS
|
|
Interneurons are part of which nervous system and have what alternative name?
|
Also called associated neurons they are part of the CNS (they are active btwn the steps of sensory and motor)
|
|
Motor neurons do what and are part of which division of the nervous system?
|
PNS; conduct signals from CNS to muscles or glands
|
|
Sensory neurons are afferent or efferent?
|
afferent
|
|
Motor neurons are afferent or efferent?
|
efferent [ME]
|
|
What are the 4 main parts of the brain?
|
1. Cerebrum: higher brain functions
2. Cerebellum: neuromuscular coordination and proprioception 3. Brainstem 4. Diencephalon: thalamus, hypothalamus, epithalamus |
|
What are the 3 main parts of the Diencephalon?
|
thalamus, hypothalamus,
epithalamus |
|
What are the 4 main parts of the cerebrum?
|
From back to front..
1. Frontal lobes 2. Temporal lobes 3. Parietal lobes 4. Occipital |
|
Frontal lobe functions
|
important for attention, executive
function, motivation, and behavior. |
|
Name some simple frontal lobe tests
|
Tests for frontal lobe
function include working memory (digit span, spelling backward), judgment, fund of knowledge, task organization and set generation such as naming lists of things in a certain category. |
|
Which lobe is important for emotional responses?
|
Temporal
(amygdala and its connections to the hypothalamus and frontal lobes) and memory (hippocampus and limbic connections) |
|
What are the main test for temporal lobe?
|
memory, specifically declarative (explicit events, facts)
|
|
Which lobe(s) are responsible for language?
|
Frontal (Broca's area) EXPRESSIVE
Frontal/Parietal (Wernicke's area, part of the brain where the frontal and parietal area meet) RECEPTIVE |
|
Parietal lobe functions
|
perception and interpretation of sensory
information especially somatosensory information |
|
If pt presented with the *inability to identify objects by
tactile exploration*, which lobe is likely affected? |
Pt has Agnosia
Parietal Lobe |
|
If pt presented with the *inability to perform purposeful motor acts on command*, which lobe is likely affected?
to draw objects? |
Pt has Apraxia; Aprada
Parietal Lobe |
|
What are common test for the occipital lobe?
|
visual fields
(see Cranial Nerve 2), naming of objects, naming of colors and recognition of faces |
|
Name 11 tests for the cerebrum and examples
|
1. Orientation, memory (3 word sets, presidents)
2. Attention, working memory (spell backwards, name months of year backwards) 3. Judgement-Abstract reasoning (what would you do if a house was on fire?) 4. Set generation (give me a set of words that begin with T) 5. Receptive language (ask pt to follow commands) 6. Expressive language (naming objects, reading comprehension) 7. Praxis (perform tasks without visual cues - wink, pretend to drink from a straw) 8. Gnosis (place object in hand, or draw letter on their hand with eyes closed) 9. Dominant parietal lobe function (ID right index finger) 10. Non-dominant parietal lobe function (draw a clock) 11. Visual recognition (what color is this) |
|
Name 3 parts of the brainstem
|
1. Midbrain
2. Pons 3. Medulla Oblongata |

Describe the spinothalamic tract
sensory/motor? afferent/efferent? origination? ant or post? white or gray matter? type of info it transmits? transmits to where? receive input from what fibers? innervate what? |
The spinothalamic tract is a sensory (afferent) pathway originating in the spinal cord.
It transmits information to the thalamus about pain, temperature, itch and crude touch. [Cone: Light touch] The cell bodies of neurons that make up the spinothalamic tract are located within the anterior portion of the spinal cord (white matter). These neurons receive input from sensory fibers that innervate the skin and internal organs. |
|
Describe dorsal column pathway (DCML)

sensory pathway responsible for transmitting fine touch, vibration and conscious proprioceptive information from the body to the cerebral cortex

|
pin (pain), bristles (light touch)

You have 1 nose, 2 eyes, and 3,4,6 makes my eyes do tricks! :This rhyme will help to remember Cranial nerve I is olfactory,II is optic and also to remember that III,IV & VI are nerves that innervate extraocular muscles attached to the eyeballs ie., cranial nerves III,IV & VI make our eyes move.
