Parts of the Brain

provides integrative power underlies complex behavior of vertebrates

· consists of neuron cell bodies, dendrites and unmyelinated axons

clusters of axons wit myelin sheaths

In spinal cord: outside- consistent with its function in linking the CNS to sensory and motor neurons of the PNSIn brain: inside- role of signaling btw neurons of the brain in learning, feeling emotions, processing sensory info, and making commands

conveys info to and from the brain and generates basic patterns of locomotion

Part of nerve circuits that produce reflexes

connect brain with locations mostly in organs of the head and upper body

run between the spinal cord and parts of the body below the head

Homeostasis, coordination of movement, conduction of info to and from higher brain centers; signals affect attention, alertness, appetite and motivation

transfer of info between the PNS and midbrain and forebrain

all axons carrying sensory info to and motor instructions from higher brain regions pass through the __

Help coordinate large-scale body movements

contains centers for receiving and integrating several types of sensory info

coded sensory info along neurons to specific regions of the forebrain

portions of this form prominent optic lobes

fromt he __ affect attention, alertness, appetite and motivation

ins centers that control several automatic, homeostatic functions, like breathing heart and blood vessel activity, swallowing, vomiting, and digestion

participates in some activitees like regulating breathing centers in the medulla

transitons between attentiveness and mental alertness are regulated by the __ and __

both arousal and sleep

The __ contains several centers for controlling arousal and sleep, like __.

acts as a sensory filter and determines which incoming info rreaches the cerebral cortex

sleep and walkefulness are also regulated by parts of the __.

The __ and _ contain centers that cause slep when stimulated and the __ has a center that causes arousal.

coordinates movement and balance

receives sensory info about position of joints and length of muscles, as well as input from the auditory and visual systems

moniteors motor commands issued by the cerebrum

info from the cerebrum passes first to the pons and then to the ++

integrates info as it carries out coordination and error checking during motor and perceptual functions

ye coordination

major integrating centers that act as relay stationss for ino flow in body

main input center for sensory info going to the cerebrum; incoming info from all the senses sorted in here and sent to approate cerebral centers

also receives inputs from the cerebrum and other parts of the brain that regulate emotion and arousal

one of most important brian regions for control of homeostasis

contains body's thermostat, and centers for regulating hunger, thirst, and moany othe rbasic survival mechansism

play a role in sexual and mating behavior , the flight or fight response, and pleasure

specialized nerve cells in here regulate cricadian rhythm and biological clocks

circadian rhythms are coordinated by a group of neurons in the __ caled the __.

info processing largely centered in here

important for planning and learning movement sequenes

vital for perception in mammal

highly convoluted __ is needed for advanced cogntion

top or outer portion of the brain

visual information in which lobe of cerebral cortex

auditory input in which lobe

somatosensory input

info about taste

olfactory

motor
perceptive
cognitive

and motor info

homeostasis
survival behavior
thermostat; appetite
thirst
circadian rhythms

info proessing

voluntary and cognitive

enables communication
