What does the Pre-frontal lobes function ?
- -Personality
- -Adaptation of the personality to events and experiences
- -Foresight and imagination
- -Sense of self
-
What is the function of the Frontal Lobe ?
Main motor areas (originate movement that is co-ordinated elsewhere)
-
What is the function of Parietal lobe ?
- -Principle sensory area
- -Touch
- -Proprioception
- -Lesions cause sensory losses
- -Involvement in cognition
- -Receptive speech loss
-
Temporal Lobe
- -Cognition
- -Emotion
- -Memory
- -Links to the hippocampus and the limbic system are important to both of the above
- -Wernicke’s area (tempero-parietal) special role in auditory association and speech comprehension
-
Occipital lobe
- -Vision
- -Visual processing and visual association
- -Involved in eye movement
- -Hemianopia from damage
-
What lobes does the lateral cerebral fissure (Sylvian fissure) separate ?
Temporal from the parietal , frontal
-
What does the circular sulcus separate ?
It separates the insula from the temporal , parietal , and frontal lobes.
-
What does the longitudinal cerebral fissure separate ?
The right and left hemispheres
-
What does the central sulcus (the fissure of Rolando) separate ?
Separates the frontal and parietal lobe.
-
What does the parieto-occipital fissure separate ? t
the parietal lobe from the occipital lobe.
-
What does the Corpus Callosum do ?
The corpus callosum connects the two hemispheres
-
What do the Transverse (commissural) fibres do ?
interconnect the two cerebral hemispheres (mainly the corpus callosum)
-
What do projection fibers do ?
Projection fibers connect the cerebral cortex with lower portions of the brain or the spinal cord.
-
What do Association fibers do ?
connect the various portions of a cerebral hemisphere and permit the cortex to function as a coordinated whole.
-
What does the Primary Motor Cortex do ?
-The primary motor projection cortex is located on the anterior wall of the central sulcus.
-These cells control voluntary movements of skeletal muscle on the opposite side of the body.
-
What is the function of the Primary Sensory Cortex ?
sensory information received from the skin, mucosa, and other tissues of the body and face is located in the postcentral gyrus and is called the somatesthetic area,
-
Why can the frontal and perietal lobes be considered a secondary sensory cortex ?
They also receive sensory stimuli .
-
Where is the cortical taste area located ?
Close to facial sensory area
-
Where is the primary Visual Cortex located ?
Occipital lobe.
- Right lobe - right half of each eye
- Left
- Top
- Bottom -
-
Where is the Primary auditory cortex ?
is located in the superior temporal gyrus toward the lateral cerebral fissure.
Wernicke's area
-
What makes up the Basal Ganglia ?
- Caudate nucleus
- Putamen
- Globus pallidus
- Corpus straitum
-
Functionally, what do the basal ganglia and their interconnections and neurotransmitters form ?
Extrapyramidal system.
-
What is the function of the Extrapyramidal system ?
- -Motor instructions
- -Stabilizes complicated systems that control movement
- -Helps to direct action and interpret sensory information
