The Central Nervous System (CNS) consists of the
Brain and spinal cord
The Peripheral Nervous System (PNS) consists of
12 cranial nerves
31 pairs of spinal nerves
Autonomic Nervous System (ANS)
Somatic Nervous System (SNS)
Sympathetic vs. parasympathetic?
Sympathetic –> Fight or Flight
Parasympathetic –> Rest & Digest
What is the function of the somatic nervous system?
Voluntary Control of Movements
What does the frontal lobe do?
Primary Motor Cortex, Personality, Behavior, Emotion, Intellect, Skilled Movement
What does the temporal lobe do?
Sounds (Perception & Interpretation), Smell
What does the parietal lobe do?
Processes sensory data
What does the occipital lobe do?
Visual Cortex & Interpretation of Visual Data
What is Broca’s area and what happens when there is a deficit to the region?
Broca’s Area –> Frontal Lobe, Left Side, Speech & Motor
Deficit to Broca’s Region (i.e. Stroke) –> Broca’s Aphasia=Paraphasia –> Person can Hear and Comprehend words but is unable to speak correctly. Incoherent words are substituted.
What is Wernike’s area and what happens when there is a deficit to the region?
Wernike’s Area –> Temporal Lobe, Left Side, Language & Comprehension
Deficit to Wernike’s Region –> Wernike’s Aphasia (AKA Receptive Aphasia) –> Person has difficulty understanding written or spoken language.
Word salad.
What is the thalamus?
The brain’s relay station
What is the hypothalamus?
The body’s thermostat. Maintains homeostasis.
What does the cerebellum control?
Coordination, Equilibrium, Posture, and Position Sense
What does the brainstem regulate?
Heart rate, breathing, and swallowing.
Where do the cranial nerves originate from?
Brainstem
What can happen if the brainstem is damaged?
Can lose the airway very quickly.
The CNS pathway has a _____________ representation.
Crossed
Left cerebral cortex receives sensory data from and controls the right side motor function.
Right cerebral cortex receives sensory data from and controls left side motor function.
What does the descending tract control and which way does it move?
Motor and DOWN to the body
What does the ascending tract control and which way does it move?
Sensory and UP to the brain
Afferent vs. Efferent
Afferent - Sensory Towards Brain
Efferent - Motor Away from Brain
VEMDAS
Ventral –> Efferent –> Motor —> Dorsal –> Afferent –> Sensory
Deep tendon reflex
Muscle tendon
Lower extremities- Patellar, Achilles, and Hamstring
Upper extremities- Triceps, Biceps, and Brachioradialis
Superficial reflex
Abdominal, Corneal (CN 5&7), Cremasteric (L1/2)
Visceral reflex
Pupillary reflex to light
