Cranial Nerves
Brain Structures
100
The most superior and largest part of the brain
What is cerebrum
100
Inferior to the center of the cerebrum, forms the superior part of the brain stem. 4 rounded masses of grey matter act as centers for certain reflexes involving the eye.
What is midbrain
100
This deep grove divides the right and left cerebral hemispheres.
What is longitudinal fissure
100
controls muscle of the tongue
What is Hypoglossal / #12
100
2 layers of connective tissue that surround both the brain and the spinal cord.
What is meninges
200
the area between the cerebral hemispheres and the brain stem. It includes the thalamus and the hypothalamus
What is dicencephalon
200
Lies between the midbrain and the medulla, anterior to the cerebellum. Connects the cerebellum with other portions of the brain. helps regulate respiration
What is Pons
200
The cortex is arranged in folds forming elevated portions
What is gyri
200
Carries impulses for the sense of smell toward the brain.
What is Olfactory / #1
200
The thickest and toughest and outer most part of the meninges
What is dura matter
300
Connects the cerebrum and diencephalon with the spinal cord. Parts include midbrain, pons and medulla oblongata
What is brain stem
300
Links the brain with the spinal cord. Has centers for control of vital functions, such as respiration and the heartbeat.
What is Medulla oblongata
300
The brain stores information which can be recalled on demand.
What is memory
300
Controls contraction of eye muscles
What is Oculomotor /#3
300
In certain places the dura matter separates into 2 layers
What is dural sinuses
400
located immediately below the posterior part of the cerebral hemispheres. It name means "little brain"
What is cerebellum
400
Has reflex centers concerned with vision and hearing.
What is midbrain
400
This lies between the frontal and parietal lobes of each hemisphere at right angles to the longitudinal fissure.
What is central sulcus
400
Controls muscles of facial expression
What is Facial / #7
400
A clear liquid that circulates in and around the brain and spinal cord
What is cerebral spinal fluid
500
The 4 regions of the brain
What is Cerebrum, Diencephalon, Brain Stem, Cerebellum
500
3 divisions of the brain stem
What is Midbrain, pons, medulla oblongata
500
Each cerebral hemisphere is divided into four visible lobes.
What is Frontal lobe, Parietal lobe, Temporal lobe, Occipital lobe
500
Controls muscles in the neck and larynx
What is Accessory / #11
500
4 ventricles that produce CSF
What is Lateral Ventricles (2), 3rd ventricle, 4th ventricle
