Chapter 12.1 Human Structure and Function

Cerebrum

Adult Brain structure in Telencephalon, In forebrain,

Diencephalon

Adult brain structure in Diencephalon, in forebrain,

Brain stem: midbrain

Adult brain structure in Mesencephalon(midbrain), heart rate and breathing

Brain stem: pons

Adult brain structure in Metencephalon, in hindbrain, heart rate and breathing

Brain stem: medulla oblongata

Adult brain Structure in Myelencephalon, in hindbrain, heart rate and breathing

Cerebral convolutions

Wrinkles, increase surface area allowing more neurons to occupy space

Gray Matter

Neuron cell bodies, external to white matter, makes up cerebral cortex

White mater

Myelinated axons

Cerebral Cortex

Outer layer of cerebrum, made of gray matter, conscious mind

Functions of Cerebral Cortex

Motor, Sensory, Association

Motor function Cerebral Cortex

Voluntary movement

Sensory function of Cerebral Cortex

Conscious awareness of sensation 

Association function Cerebral Cortex

Processes and connects information to help you think

3 Parts of Diencephalon

Thalamus, Hypothalamus, Epithalamus

Thalamus

Part of Diencephalon, sensory integration

Hypothalamus

Part of Diencephalon, Homeostasis

Epithalamus

Part of Diencephalon, Made of pineal gland that secretes melatonin helping sleep

Brainstem

Autonomic Functions
