Chapter 3 Lesson 2 Flashcards
The nervous system divided by two which one are they?
Central nervous system and peripheral nervous system
What is the CNS composed of?
Brain and spinal cord
What is PNS composed of?
Nerves
somatic ns
Relays sensory and motor information to and from the CNS
Automatic ns
Controls our internal organs and glands
Symphatetic ns
Controls body when its aroused
Parasymphatic ns
Controls body during its normal rest state
Corpus callousness
Allows the two hemispheres to communicate with each other
Which part are the two hemispheres part of?
Forebrain
The four lobes of the forebrain
Frontal lobe, parietal, temporal, occipital
What is the frontal lobe?
Reasoning,motor control, emotion, language
Parietal lobe
Process info from the body’s senses
Temporal lobe
Hearing, memory, emotion
Occipital lobe
Visual
What lobe is the prefrontal cortex and meaning?
Frontal and responsible for executivefunctioning
Motor cortex
Involved in planning and coordinating movement frontal lobe
Broccis area
Process language- frontal
Somatosensory cortex
Process info from across the body, touch, temperatures and pain - parietal lobe
Auditory cortex
Temporal lobe- the main are responsible for processing auditory info
Wernicke’s area
Speech comprehension - temporal lobe
Visual cortex
Responsible for interpreting visual info
Thalamus
Relays info from senses -all senses are rooted through the thalamus except smell
Limbic system
Process emotion and memory
Hip thalamus
Regulates a number of homeostatic process including body temperature, hunger, blood pleasure
Amygdala
Fear and treat recognition
Hippocampus
Structure from learning and memory
What part is the reticular formation and meaning
Midbrain, regulates sleep/wake cycle
Medulla
Control breathing, blood pleasure, heart rate
Pons
Regulates brain activity during sleep
Cerebellum
Control balance, coordination-movement, motor skills
