Introduction To Neuroanatomy Flashcards
Which two parts make up the forebrain?
Cerebrum and diencephalon
Which three parts make up the brainstem?
Midbrain
Pons
Medulla
What is the function of the corpus callosum?
Allows communication between hemispheres of the brain.
Highly myelinated axons
What are the major functions of the midbrain?
Coordination of eye movement and response of pupils to light
What are the major functions of the pons?
Feeding (trigeminal nerve supply to muscles of mastication) and sleep regulation
What are the major functions of the medulla?
Cardiovascular and respiratory control
What functions are controlled by the frontal lobe?
Voluntary motor control Speech Social behaviour Higher cognition Impulse control
What functions are controlled by the parietal lobe?
Somatosensory perception
Spatial awareness
What functions are controlled by the occipital lobe?
Visual perception
What functions are controlled by the temporal lobe?
Language Emotion Long term memory Smell Hearing Taste
What functions are controlled by the cerebellum?
Coordination and motor learning
Where is the primary motor cortex located?
How are parts of the body mapped to it
Precentral gyrus of the frontal lobe
Lateral to medial - tongue, face, hands, arms, trunk, legs, feet, genitals
Where is the primary somatosensory complex located?
Post central gyrus of the parietal lobe
What type of control do spinal nerves exhibit?
What does this mean?
Uni cortical control?
Pathways connecting motor cortex on one side link to spinal nerves controlling the limb on one side
Where do spinal nerves cross over?
Lower medulla (contralateral cortical control)
