CH 12 : Brain (Final Exam) Flashcards
What is included in the External and Internal Brain Structures?
Tellencephalon, Diencephalon, Brain Stem. & Cerebellum
The Telencephalon has ?
Two Cerebral Hemispheres ; Most Top
what is in the Telecephalon?
Longitudinal fissure, Sulcus, Brain Lobes,& Olfactory Bulbs
What is the function of the Longitudinal Fissure?
Divides brain into left & Right hemispheres
What is the function of the Sulcus?
Divides Brain into different gyri & lobes ; shallower than Fissure
What is the function of the Central Sulcus ?
divides Frontal lobe from Parietal Lobe
What is the Function of the Lateral Sulcus?
Divides Frontal Lobe from Temporal Lobe
What are the 5 Brain Lobes?
Frontal, Parietal, Occipital, Temporal, & Insula
Where is the Insula located?
Part of Cerebral Cortex; Within Lateral Sulcus
What are the Functions of the cerebrla Cortex?
- Sensory Cortex; 2. Motor Cortex
What is within the Sensory Cortex?
General Sense; Special Sense
Where can Genral sense be found?
- Everywhere
- in postcentral gyrucs of Parietal lobe
What is considered General Sense?
- Pain, Pressure, Touch, Temperature, & Pacinia
PPTT
How does Somatosensory sensation work?
The larger area, the better sensed
What is included in Special Senses?
- Visual Cortex.
- Auditory Cortex
- Olfactory Cortex
What happenes when the General Sense is damaged?
Losses Sense ONLY ( Still has function)
