The Diencephalon & The Cerebellum: Test 4

What are the 4 divisions of the brain?

cerebrum, diencephalon, cerebellum, brainstem

The ________________ is located in the center of the brain and is hidden almost completely by the cerebral hemispheres in an external view. Consists the thalamus, hypothalamus, epithalamus, subthalamus

diencephalon

The _______________ consists of two-oval shaped masses and acts like a “gateway” for signals traveling to the cerebral cortex.

thalamus

The ______________ is shaped like a funnel and is located anterior and inferior to the thalamus. it plays an important role in homeostasis and regulating the endocrine system.

Hypothalamus

The ______________ is not pat of the diencephalon, it is anatomically and functionally linked to the hypothalamus. It is connected to the hypothalamus by a short stalk called _________________. The hypothalamus regulates the activity of the pituitary gland.

pituitary gland

infundibulum

The ____________ is an endocrine organ that produces the hormone melatonin

pineal gland

The _____________ is located at the posterior and inferior portion of the brain. Functions include coordinating muscle movements.

Composed of two hemispheres that are connected by a __________.

The ridges in the cerebellum are called __________ ________.

White matter called __________ __________ connect the cerebellum to the brainstem and information flowing into or exiting the cerebellum travels along the fibers of the peduncles.

cerebellum

vermis

folia

arbor vitae
