Human Brain Anatomy D142-D143
the brain has 2 Hemispheres divided by Longitudinal Fissure
The Cerebrum and Cerebellum are divided by Transverse fissure
Cerebral Cortex is often referred to as Gray Matter
There is a frontal lobe
Parietal lobe
Occipital lobe (vision)
Temporal lobe (auditory function)
The frontal lobe and temporal lobe are separated by lateral sulcus
Insula, which you have to pull out Temporal Lobe
Insula (Taste preception)
Central Sulcus runs from Longitudinal fissure to Lateral Sulcus
Precental Gyrus in anterior to the Central Sulcus
Precental Gyrus (It recieves Somatic sensory like touch, pain, pressure, etc)
Corpus Callosum, bundles of Fibers in Copus Callosum allowing left and right Hemispheres to "talk" to each other
Bellow that is the Septum Pellucidum, it separates Lateral Ventricles
^^Down bellow that is the Fornix
^^ Down again, we have the Diencephalon, which includes Thalamus and Hypothalamus
That Thalamus, it acts a relay station on sensory info
The floor of Thalamus is Hypothalamus
It forms the link between the Nervous and Endocrine system
The round right in the middle of the Thalamus is the Massa Intermedia connects the two Thalami
It will connect the left and right thalamus together , allowing the thalamus to communicate
Choroid Plexus, which secretes Cerebral Spinal Fluid (CFS)
Pituitary Gland and Hypothalamus communicates with the Gland via
Infundibulum
Right above is the Optic Chiasm, that is where two Optic Nerves cross
Pineal Gland, secretes Melantonin hormone
The hormone level goes up to stimulate sleep, and lights inhibit this hormone secretion
Third Ventricle is right at the Indentation
Brain stem
Brains Stem consists of Midbrian, Pons, and medulla Oblongata
Midbrain (Mesencephalon), is located below the Hypothalamus
The mamillary body that controls feeding reflexes such as licking, and swallowing
Posterios to the Midbrain is the Corpora quadrigemina, which consists of superior and inferior colliculi
Superioir colliculi are for visual stimuli and inferior colliculi are for auditory stimuli
The canal is called Cerebral Aqueduct or Aqueduct of Midbrain
It drains CSF from 3rd to 4th ventricle
