Unit 2 test (brain extra) Flashcards
Serotinin
neurotransmitter that helps regulate sleep, moods/emotions
Dendrite
The part of the neuron that receives messages from other neurons
Axon
The part of the neuron that sends messages to other neurons
Neurons
Cells in nervous system
Dendrite to Axon terminal
direction of the neural impulse within one neuron.
Dendrite, Cell body, Axon
direction an electrical signal moves
Synapse
microscopic gap between neurons
Neurotransmitter
chemical messenger
Main divisions of the nervous system
peripheral and central
The central nervous system made up of
The brain and spinal cord
Cerebellum main function
muscle coordination
Medulla oblongata (responsibilities)
Heartbeat, breathing, and blood pressure
Frontal lobe (Controls)
Abstract thought and emotional control
Autonomic nervous system
Automatic functions of the body/ involuntary response
Temporal Lobe
Controls hearing, and language comprehension
Occipital lobe
Visual processing
-Deals with vision
contains visual cortex
Peripheral nervous system
The part of the nervous system that consists of nerves that branch out from the CNS (central nervous system) and connect to other body parts
Cerebellum (Complex def)
This area is in charge of balance and coordinating movements.
Cerebral Cortex
Wrinkled part of the brain’s surface where the body processes information
Parietal Lobe
Possesses the Sensory Cortex
Broca’s Area
Area of cerebrum that allows us to speak (Speech production)
Frontal lobe (complex def)
Makes decisions, plans, reasons, and carries out behaviors
A person has a stroke on her occipital lobe. What might happen to her?
blindness
If an organism did not have a well-developed frontal lobe, like a grasshopper, what functions would it have issues with?
Problem solving
Amygdala (complex def)
part of the Brain plays an important role in emotions, especially fear
Hippocampus
involved in the processing and storage of memories.
Hypothalamus
Controls and regulates Body temperature, Sexual Arousal, Hunger, Thirst, Endocrine System
Frontal lobe contains
Motor cortex and Broca’s area
Broca’s Aphasia
unable to make movements to talk.
-Damage to Broca’s area
Temporal lobe contains
Wernicke’s area
Wernicke’s area
interprets written and spoken speech.
Wernicke’s Aphasia
unable to understand language: the syntax and grammar jumbled.
Sensory cortex
receives incoming touch sensations from rest of the body.
