Brain Stuff Pt.1 Flashcards
What controls internal functions reacting to the out side-world, learning & memory and converts new info. Into storage
Nervous system
Brain and spinal cord
Central nervous system
What controls messages from the body to the brain
Peripheral nervous system
Most common part is a nerve cell
Peripheral nervous system
Transmits sensory info.to the central nervous system
Somatic nervous system
Activated by temp. Change, touch, pain,and changes in body position
Somatic nervous system
Regulates vital functions
Autonomic nervous system
Receives messages, has many dentrites, and one axon
Neuron
Produces energy that fuels the activity of the cell
Cell body
Fibers that branch out from the cell body, receives info. From other neurons,and passes messages through the cell body
Dentrites
Carry messages away from the cell
Axons
Insulate and protect axons
Myelin
Junction between the axon terminals of one neuron and the dentrites of another
Synapse
Neurons sending messages across synapses through chemical stored in sacs in the axon terminal
Neurotransmitters
Vital structures such as heart rate, breathing, and blood pressure are controlled by this part of the brain which is located where?
Medulla / hindbrain
Located infront of the medulla, this regulates body movement , attention, sleep, and alertness . where is this located?
The pons/hindbrain
What part of the brain is responsible for balance and coordination, it is also known as the “little brain” where is it located?
Cerebellum/hindbrain
Located behind hindbrain and forebrain
Midbrain
Involved in vision and hearing
Midbrain
Where is the reticular activating system
Midbrain
What is responsible for attention, sleep and arousal
Reticular activating system
What relays info to a higher level of the brain, where is it located?,
Thalamus/ forebrain
What part of the brain is vital for hunger, body temp. ,Storage of nutrition aggression and carrying for off spring, where is it located
Hypothalamus/forebrain
What is responsible for learning, memory, emotion, hunger, sex, and aggression?
Limbic-system
