Nervous system Part 1 & 2

Muscle contractions and gland secrertions

The Brain and spine

all peripheral nerves(all cranial and spinal nerves

Central nervous system and peripheral nervous system

The four lobes(cereberal hemispheres), thalamus, hypothalamus, brain stem, and cerebellum

Frontal, Parietal, Temporal, and Occipital

takes in all sensory info except smell

maintaining homeostasis but also maintaining bodily tension to change behavior Ex. giving the feeling of hunger so someone eats

The pons, Midbrain, and medulla

muscle memory/ automated muscle actions Ex. speaking, writing, walking

by meninges

by epineurium

actually the epineurium Ex. standing toe touch

pinky or index finger

motor and sensory neurons

efferent aka they send signals away from the brain

afferent aka they send signals to the brain

somatic and autonomic

skeletal muscles

smooth muscles, cardiac muscles and glands

sympathetic and parasympathetic nervous system

the fight or flight response ex. dilated pupils, higher heart rate, high blood pressure

responsible for rest and digestion ex. undilate pupils, lower heart rate, lower blood pressure

innervated part of the meninges

Mechanoreceptive neurons
Nociceptive
Smell
Sight
Sound
Taste
Vestibular

Muscle spindle and Golgi tendon organ

detect muscle stretch

detect muscle tension

peripheral phenomenon, raw data from sensory receptors

central phenomenon, conscious experience of what's happening

detects actual or potential tissue damage

touch

movement of the head

mechanoreceptors, visual info, and vestibular apparatus/nerve to give a sense of balance
