Module 5- The Brain Flashcards
What is the thalamus
The brains sensory switchboard, located on top of the brainstem it direct messages to the sensory receiving areas in the cortex
What is the brain stem?
The oldest part and central core of the brain. It begins where the spinal cord swells as it enters the skull. It includes the medulla, reticular formation, thalamus and cerebellum.
What is the cerebellum?
The little brain attached to the rear of the brainstem and help coordinate voluntary movement and balance if damage the person could perform basic movements but would lose fine coordination skills
What is the Medulla?
Located at the base of the brainstem controls basic life support functions like heartbeat and breathing
What is the reticular formation
A nerve network in the brainstem that plays an important part in control and wakefulness and arousal damage can cause a coma
What is the frontal lobe
The portion of the cerebral cortex lying just behind the four head that is involved in planning and judgment it includes the motor cortex
What might happen if you cerebellum is damaged
If damaged you could perform basic movements but would lose fine coordination skills
What is the limbic system?
The limbic system is a ring if structures at the border of the brainstem and cerebral cortex. The limbic system helps to regulate important Functions such as memory fear aggression hunger and thirst
What does the limbic system include?
The limbic system includes the hypothalamus the hippocampus and the amygdala
What is the hypothalamus?
The hypothalamus is a neutral structure lying below the Salamis. It helps regulate many of the bodies maintenance activities, such as eating, drinking and body temperature and is linked to emotion
What is the hippocampus
The hippocampus is a neural center located in the limbic system that wraps around the back of the Thalamus; it helps process new memories for permanent storage. Resembles a seahorse
What is the brains wrinkled outer surface called?
The cerebral cortex
What is the cerebral cortex?
And intricate fabric of interconnected neurons that make up the bodies ultimate control and information processing center
What is the most dramatic feature of the cortex
The longitudinal fissure
What is a longitudinal fissure
A crevice that divides the cerebral cortex into two halves called hemispheres
What is the corpus callosum?
The carpets Kausen is a large band of neural tissue that connects the two brain hemispheres and allows them to communicate with each other
How many lobes does the brain have and what are they called?
The brain has four lopes frontal parietal and temporal and occipital.
What is the parietal lobe?
The portion of the cerebral cortex lying at the top of the head and toward the rear; includes the summer sensory cortex and general association areas use for processing information
What is the occipital lobe?
The portion of the cerebral cortex lying at the back of the head includes the primary visual processing areas of the brain
What is the temporal lobe
The portion of the cerebral cortex lying roughly above the ears; it includes the auditory areas of the brain
What is the spinal cord
Tail that extends down from the brain
What is the amygdala
And almond shaped neutral cluster in the limbic system that controls emotional responses, such as fear and anger
What is the motor cortex
The motor cortex is a strip of tissue on the rear edge of the frontal lobe controls voluntary movement of your body parts
What type of pattern does the motor cortex control
Different points on the motor cortex control different parts of your body but they do so in a curious cross wired pattern. Thus the motor cortex of your right hemisphere takes care of moving on the left side of your body, and the motor cortex in your left hemisphere controls movement on the right side of your body.
