Brain Flashcards
If someone is left brain dominant, which side of the brain would the speech and language centers be located?
Left side
Where is the primary motor cortex located?
Frontal lobe directly anterior to central sulcus
Which lobe of the brain deals with personality, planning, thinking, and voluntary movement?
Frontal lobe
What portion of the brain is used for coordinated movement/coordination?
Cerebellum
How many neurons are involved in a dorsal column?
3
Which spinal pathway is a descending efferent pathway responsible for voluntary movement?
Lateral Corticospinal tract
The right side of the field of view is interpreted by what side of the brain (vision)?
Left side of brain
Which lobe of the brain deals with hearing?
Temporal
Which artery distributes to the inferior aspect of cerebral hemisphere and occipital lobe?
Posterior cerebral
Does the internal carotid go through the foramen lacerum?
No runs over it
Which artery distributes to the cerebral arterial circle (or willis)?
Anterior communicating
Which artery distributes to the cranial meninges and cerebellum?
Vertebral
Which artery distributes to most of the lateral surface of the cerebral hemispheres?
Middle cerebral
Which spinal pathway is a ascending afferent pathway responsible for sensing crude touch, pain, and temp?
Spinothalamic tract
Which artery distributes to the brainstem, cerebellum, and cerebrum?
Basilar
How many neurons are involved in a corticospinal tract?
2
Which artery gives branches to walls of cavernous sinus, pituitary gland, and trigeminal ganglion; provides primary supply to vein?

3
Where does the neuron cross over in a corticospinal tract?
Medulla
Which spinal pathway is a ascending afferent pathway responsible for sensing vibration, fine touch, and position?
Dorsal column
Where is the primary sensory cortex located?
Parietal lobe directly posterior to central sulcus
What are the 3 branches of the internal carotid artery?
Anterior cerebral, anterior communicating, and middle cerebral
Which artery distributes to the optic tract, cerebral peduncle, internal capsule, and thalamus?
Posterior communicating
Which artery does not give off any branches until it gets into the cranium?
Internal carotid
Which hemisphere of the brain is dominant in most human?
Left Brain
Which lobe of the brain deals with sensory processing, has map of the body for sensory purposes; deals with pain, temp, and propriocetion
Parietal lobe
Which artery distributes to the cerebral hemispheres except for occipital lobe?
Anterior cerebral
Where does the neuron cross over in a spinothalamic tract?
Spinal cord
What are the 3 branches of the vertebral artery?
Basilar, posterior cerebral, and posterior communicating
Where does the neuron cross over in a dorsal column?
Medulla
