medulla oblongata

acts as the conduction pathway between the brain and the spinal cord. It contains nuclei that regulate autonomic functions, such as respiration

pons

bridges the two main function areas of the central nervous system and forms part of the brain stem. It's continuous with the medulla oblongata

brain stem

connects the spinal cord to the higher-thinking centers of the brain. it consists of the medulla oblongata, pons, and midbrain

sulci

depressions

longitudinal fissure

divides cerebral hemispheres

cerebellum

fine tunes the movement of the body and manages balance and posture

pia mater

innermost, closely follows cerebral contours

cerebrum

largest part of the brain and allows the body to consciously control its actions. it's divided into two hemispheres, each with four lobes

arachnoid

middle, web-like layer

when the cerebellum is pulled away what can be seen ?

pineal gland - point in between hemispheres superior and inferior colliculi (buttcheeks)

diencephalon

region of the forebrain with three distinct structures, the thalamus, hypothalamus, and epithalamus. These structures contribute to learning and memory, the regulation of autonomic nervous system functions, emotions and behavior, food consumption, and body temperature and circadian rhythms

gyrus

ridges

transverse fissure

separates cerebrum from cerebellum

pituitary gland

small endocrine gland that secretes and stores hormones that manage endocrine system functions. it's attached to the end of the infundibulum of the hypothalamus and has two lobes

dura mater

thick, outermost layer of the meninges

cerebellum contains

vermis
