voluntary muscle movements

Question 17

Parietal lobe

Answer 17

somatosensory functions
touch,taste
process info abt body position

Question 18

Temporal lobe

Answer 18

auditory receptors (hearing)
Wernick’s area ( language comprehension)

Question 19

Occipital lobe

Answer 19

Vision interpretation by processing visual information

Question 20

Broca’s aphasia

Answer 20

happens from brain damage which leads to language impairments
patients are unable to to produce fluent speech but can understand what others are saying

Question 21

Wernick’s aphasia

Answer 21

patient can produce fluent speech but do cant put that understatement into speech

Question 22

PNS

Answer 22

Peripheral Nervous System, nerves that link CNS to rest of body including sensory organs muscles glands and internal organs

Question 23

PNS two main divisions are

Answer 23

somatic system and autonomic system

Question 24

aThe somatic system is

Answer 24

voluntary control
carries info from sensory receptors to skeletal muscle

Question 25

The autonomic system is

Answer 25

the involuntary control, maintaining homeostasis (breathing heart rate)

Question 26

Subdivisions of autonomic system are

Answer 26

sympathetic and parasympathetic stress(fight or flight) and rest and digest basically

Question 27

sympathetic division of autonomic system is activated

Answer 27

during stressful situations release of epinephrine and norepinephrine

Question 28

parasympathetic subdivision of autonomic system is actived

Answer 28

when body is calm and at rest releases acetylcholine

Question 29

what happens w organs during sympathetic subdivision of autonomic system is activated heart digestive tract liver eyes bladder skin respiratory system

Answer 29

increased heart rate decreased peristalsis (swallowing) increased glucose release (for energy use) dilated pupils inhibits urination decreased blood flow to skin>goes to muscles dilates bronchioles (to take in air)

Question 30

What happens w organs duribg activated parasympathetic system heart digestive tract liver eyes bladder skin respiratory tract

Answer 30

decreased heart rate increased peristalsis; swallowing stores glucose (dont need energy) constricts pupils promotes urination increases blood flow constricts bronchioles
