Divisions of the Brain
The largest part of the brain
What is cerebrum
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
This deep grove divides the right and left cerebral hemispheres.
What is longitudinal fissure (or corpus callosum)
controls muscle of the tongue
What is Hypoglossal / #12
2 layers of connective tissue that surround both the brain and the spinal cord.
What is meninges
the area between the cerebral hemispheres and the brain stem. It includes the thalamus and the hypothalamus
What is dicencephalon
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
The cortex is arranged in folds forming elevated portions
What is gyri
The thickest and toughest and outer most part of the meninges
What is dura matter
Connects the cerebrum and diencephalon with the spinal cord. Parts include midbrain, pons and medulla oblongata
What is brain stem
Links the brain with the spinal cord. Has centers for control of vital functions, such as respiration and the heartbeat.
What is Medulla oblongata
This lobe on the cerebrum is the main center for vision
What is occipital
this is the white matter within the cerebellum that gives it a tree-like appearance
What is arbor vitae
located immediately below the cerebral hemispheres, specifically the occipital lobe. It name means "little brain"
What is cerebellum
Has reflex centers concerned with vision and hearing.
What is midbrain
This lobe is the main center for perception and trying to make sense of the world around you
A clear liquid that circulates in and around the brain and spinal cord
What is cerebral spinal fluid
The 4 regions of the brain
What is Cerebrum, Diencephalon, Brain Stem, Cerebellum
3 divisions of the brain stem
What is Midbrain, pons, medulla oblongata
Each cerebral hemisphere is divided into four visible lobes.
What is Frontal lobe, Parietal lobe, Temporal lobe, Occipital lobe
These are the shallow groves on the cerebrum
Sulci (sulcus)
