Lesson 6.3 - learning the key terms

cerebellum

section of the brain that coordinates Body movements, including balance

cerebrum

the largest part of the brain, consisting of the left and right hemispheres

diencephalon

area of the brain that includes the Epithalamus, thalamus, metathalamus, and hypothalamus, also known as the inter brain.

epithalamus

the uppermost portion of the diencephalon, which includes the pineal gland and regulates sleep-cycle hormones

fissures

the uniformly positioned, deep grooves in the brain

frontal lobes

sections of the brain located behind the forehead

hypothalamus

a portion of the diencephalon, which regulates functions such as metabolism, heart rate, and blood pressure,

lobes

the name for the 4 regions of the brain- frontal , parietal, occipital, and temporal

medualla Oblongata

the lower portion of the brain stem, which regulates heart rate, blood pressure, and breathing, and controls several reflexes

meninges

three protective membranes that surrounds the brain and spinal cord.

midbrain

relay station for sensory and motor impulses, located on the superior end of the brain stem

occipital Lobe

sections of the brain located behind the parietal lobes, intergrate sensory info from the skin, interanl organs, muscles, and joints

parietal lobes

section of the brain located behind the frontal lobes, intergrates sensory information from the skin, interanl organs, muscles, and joints

pons

the section of the brain located below the midbrain that plays a role in regulating breathing

primary motor cortex

outer region of the brain in the frontal lobes that sends neural impulses to the skeletal muscles

primary somatic sensory cortex

outer region of the brain in the parietal lobes that interprets sensory impulses relieved from the skin, internal organs, muscles, and joints.

spinal cord

a column of nerve tissue that extends from the brain stem tot eh beginning of the lumbar region of the spine

temporal lobes

the most inferior portion of the brain, responsible for hearing, speech, vision, memory, and emotions

thalamus

the largest portion of the diencephalon, which communicates sensory and motor info between the body and cerebral cortex
