The Brain

General Information

• Runs all aspects of the body• Voluntary• Involuntary• Reasoning• Intelligence• Communication

• Divided up into 3 parts• Cerebrum• Cerebellum• Brain Stem

Cerebrum

• General Reasoning• “Identifies” the person• “Soul?”

Cerebrum

Function

Lobes

Fissures & Sulcus

Function

• Senses• Motor Skills• Emotions• Consciousness• Memory• Divided into 4 Lobes by 3 fissures/sulcus

Lobes

Fissures & Sulcus

Fissures & Sulcus

• Longitudinal Fissure–Separates two hemispheres

• Central Sulcus–Separates the frontal from the parietal lobe

• Lateral Fissure–Separates the temporal from the frontal &

Parietal

Cerebellum

• Movement• Muscle actions• Voluntary & Involuntary

Cerebellum Function

Brain Stem

Function

Functions

• Equilibrium• Position• Muscular coordination• Fine Motor Movements• Muscle Tone• Posture

Cerebellum Function

Brain Stem

Function

Brain Stem

• Basic Body Functions• Involuntary Control

Function

Cerebellum Function

Brain Stem

Function

Brain Stem Divisions

• Thalamus• Hypothalamus• Pineal Gland• Mid Brain• Pons• Medulla

Cerebellum Function

Brain Stem

Function

Thalamus

• Processes Sensory Impulses• Appropriate Motor Responses to Sensory

Impulse• Consciousness• Sensory Relay station to Cerebral Cortex

Cerebellum Function

Brain Stem

Function

Hypothalamus

• Emotions• Autonomic Reactions to Emotions

(Primitive Brain)• Body Temperature• Water Balance• Appetite• Sexual Arrousal

Cerebellum Function

Brain Stem

Function

Pineal Gland

• Produces melatonin• Diurnal cycles (Day & Night)• Influences the start of puberty

Cerebellum Function

Brain Stem

Function

Mid Brain

• Involuntary movements in response to visual and auditory stimuli (reflex)

Cerebellum Function

Brain Stem

Function

Pons

• Respiration• Somatic and Visceral Reflexes• Regulates arousal, wakefulness, alertness

Cerebellum Function

Brain Stem

Function

Medulla

• Respiration• Heart Rate• Vasomotor functions• 2-way communication between higher brain

functions and spinal cord• Voluntary movement related
