Brainsten.

medulla Oblangata - controls automatic functions

Olives - relays info from the spinal cord to the cerebellum

Pyramind - motor fibers that cross over and controls OPPOSITE Side of the body.

Cardiovascular Center - regulates heart rate,blood pressure and the diameter of blood vessels.

Respiratory Center - Controls Rate and rhythym of breathing

Pons- regulates breathing: Connects cerebellum and cerebrum. (transmit info) (Bridge)

Cerebellar Peduncles- connects cerebellum and brainstem

Midbrain - vision, hearing, motor control arousal

tempt regulation

Substantia Nigra- produces do pamine (rewards)

• in the basal ganglia- invowed in movement

Retular formation- regulates sleep and alertness Corpora Quadrigenima reflexes, vision + hearing

→ Superior Collicalli - (2x) eye!

Inferior Colliculli- (2x) ear!

Cerebellum- balance motor control

Arbor Vitae- transmits signals to and from the Cerebellar cortex

Folia-increases surface area for more neuron

Cerebellar Cortex process information + Coordinating voluntary

movement.

Vermis-posture and locomotion and Connects two hemispheres

Thalamus - every sense. but smell

Epithalamus - pineal gland (melatonin) " Circadian rhythm

Hypothalamus - Homeostasis; thirst, hunger circadian rhythms

Cerebrum- thougnt, action and sensory left hemisphere -languge, analytical tasks right hemisphere-creativity

cortex - cognitive tasks, voluntary muscle control, sensory perception → frontal lobe- reasoning, problem solving

temporal lobe-language comprehension and memory formation

→ Parietal lobe-touch, tempt. pain

›Occipital lobe- visual provessing

longhitudinal Fissure grave thai seperates L+ R hemisphere

Centras sulcus- seperates frontal + parietal lobe

Lateras sulcus- Separated temporal from frontal and parietal lobe.

Preventral gyRus- motor

Postentral gyRus. Somatosensonsory

Corpus collosum- fiber that connect L+R hemispheres. fornix- Carries signals fromthe hippocampus.

Basal Nuclei - movement + coordination

memory!

Motor Areas - voluntary movement

SensoRy Areas - SensoRy inpuT

Limbic System-emotion +memoey+ motnation

hippocampus - memoRy amygdala- fear → emotion

Pituitary master gland controls other glands

Pineal gland secretes melatonin regulates sleep and circadian rhythm
