Human Brain words to know

Question 1

Cerebrum

Answer 1

the largest portion of the brain. It encompasses about two-thirds of the brain mass and lies over and around most of the structures of the brain.

Question 2

Cerebellum

Answer 2

located at the bottom of the brain, with the large mass of the cerebral cortex above it and the portion of the brainstem called the pons in front of it.[3] It is separated from the overlying cerebrum by a layer of leathery dura mater; all of its connections with other parts of the brain travel through the pons

Question 3

Pons

Answer 3

part of the brainstem that links the medulla oblongata and the thalamus.[1] In full it is pons Varolii named using the Latin word for “bridge”

Question 4

Medulla oblongata

Answer 4

the lower half of the brainstem, which is continuous with the spinal cord, the upper half being the pons. It is often referred to simply as the medulla

Question 5

Diencephalon

Answer 5

Diencephalon is the region of the embryonic vertebrate neural tube that gives rise to posterior forebrain structures including the thalamus, hypothalamus, posterior portion of the pituitary gland, and pineal gland

Question 6

Right / Left hemisphere

Answer 6

The longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum. The hemispheres exhibit strong, but not complete, bilateral symmetry in both structure and function

Question 7

4 Lobes (P, F, T, O)

Answer 7

Paritel, frontal, temporal, occipital

Question 8

3 sulci (C, L, P-O)

Answer 8

centeral sulcus, lateral sulcus, parieto occipital sulcus

Question 9

Longitudinal fissure

Answer 9

the deep groove that separates the two hemispheres of the vertebrate brain.

Question 10

Post- / Pre- Central gyri

Answer 10

postcentral gyrus is a prominent structure in the parietal lobe of the human brain and an important landmark. It is the location of the primary somatosensory cortex, the precentral gyrus is the convolution of the frontal lobe that is bounded in back by the central sulcus and that contains the motor area

Question 11

Thalamus

Answer 11

is a midline symmetrical structure of two halves, within the vertebrate brain, situated between the cerebral cortex and the midbrain

Question 12

Hypothalamus

Answer 12

located below the thalamus, just above the brainstem.

Question 13

Epithalamus

Answer 13

The epithalamus is a (dorsal) posterior segment of the diencephalon (a segment in the middle of the brain also containing the hypothalamus and the thalamus)

Question 14

Pituitary gland

Answer 14

It is a protrusion off the bottom of the hypothalamus at the base of the brain, and rests in a small, bony cavity

Question 15

Midbrain

Answer 15

The midbrain is located below the cerebral cortex, and above the hindbrain placing it near the center of the brain

Question 16

Arbor vitae

Answer 16

located deep in the cerebellum. Situated within the arbor vitae are the deep cerebellar and the fastigial nuclei

Question 17

Corpus callosum

Answer 17

a wide, flat bundle of neural fibers beneath the cortex in the eutherian brain at the longitudinal fissure. It connects the left and right cerebral hemispheres

Question 18

Cerebral cortex (gray matter)

Answer 18

Grey matter is distinguished from white matter, in that grey matter contains numerous cell bodies and relatively few myelinated axons,

Question 19

Cerebral white matter (deep)

Answer 19

consists mostly of glial cells and myelinated axons that transmit signals from one region of the cerebrum to another and between the cerebrum and lower brain centers
