Cerebral Hemispheres
This deep sulcus divides the left and right hemispheres of the brain.
What is the longitudinal fissure?
The cranial nerve that is responsible for the sense of smell.
What is the olfactory nerve (CNI)?
This transmits information through the nervous system in generating and conducting electrical pulses.
What is a neuron?
These structures are found originating in the brainstem and inserting into various parts of the face and neck.
What are the cranial nerves?
This artery supplies blood to most of the lateral surfaces of the cerebral cortex.
What is the middle cerebral artery?
This lobe of the brain is found deep to the frontal, temporal, parietal, and occipital lobes.
What is the insula?
The cranial nerve that controls eye movements
What is the Oculomotor nerve (CN III)?
They receive incoming signals from other neurons and transmit them to a neuron's cell body
What is a dendrite?
The brainstem is connected to this structure superiorly.
What is the spinal cord?
This artery is the main supplier of blood to the occipital lobe.
What is the posterior cerebral artery?
The primary motor and somatosensory cortices are arranged in this fashion.
What is somatotopic representation?
The cranial nerve that is responsible for transmitting sound and equilibrium information from the inner ear to the brain.
What is the vestibulocochlear nerve (CNVIII)?
This insulates axons and speeds up the transmission of the electrical pulses along the neuron.
What is the myelin sheath?
In reference to the brainstem, the term ventral means the same as this other directional term.
What is dorsal?
Known as the “Circle of Willis,” this arterial structure provides a protective redundancy for cerebral blood flow.
What is the cerebral arterial circle?
The surface topography of the cerebral hemispheres is composed of this kind of matter.
What is gray matter?
The cranial nerve that controls most of the facial muscles for expressions.
What is the Facial nerve (CN VII)?
The neurons communicate between other neurons within the central nervous system
What are interneurons?
This bulging portion of the brainstem is considered the mid-point.
What is the pons?
These two major arteries ascend through the neck and supply blood to the brain, uniting at the base of the brain.
What are the vertebral arteries?
This matter connects cells within the brain deep to the gray matter.
What is white matter?
The cranial nerve that innervates the heart, lungs, and digestive tract.
What is the Vagus nerve (CN X)?
The junction between two neurons where neurotransmitters are released to transmit signals from one neuron to another.
What is the synapse?
The brainstem is found anterior to this cranial structure.
What is the cerebellum?
This large sinus, located in the dura mater, drains blood from the brain and directs it towards the jugular veins.
What is the superior sagittal sinus?
