Front (Question)

Sulcus

Back (Answer)

Shallow grooves that form “valleys” on the brain’s surfaces.

Front (Question)

Gyrus

Back (Answer)

Gyri (plural) are thick folds that form “hills” on the brain’s surfaces. Also called convolutions.

Front (Question)

Fissure

Back (Answer)

Deep groove (deep sulcus)

Front (Question)

Cerebrum

Back (Answer)

The largest part of the brain. Contains 5 lobes, but we only learn 4.

Front (Question)

Cerebellum

Back (Answer)

Often called the “little cerebrum”. Helps to coordinate the skeletal muscle movements by monitoring equilibrium and balance. Has other jobs also.

Front (Question)

What part of the brain is found in the inferior and posterior part of the skull (head)?

Back (Answer)

The cerebellum. Locate the cerebellum and you know you are viewing the posterior of the brain.

Front (Question)

Name the most anterior portion of the brain.

Back (Answer)

The cerebrum.

Front (Question)

Nuclei of the brain

Back (Answer)

Areas of gray matter found in the inner portion of the brain. Function in integration (processing information and making decisions).

Front (Question)

Blood brain barrier

Back (Answer)

Prevents many substances from flowing into the brain. Allows glucose and oxygen, and a few drugs such as alcohol and nicotine. Prevents many therapeutic drugs.

#10

Front (Question)

Corpus callosum

Back (Answer)

A tract of nerve fibers connecting the left hemisphere with the right hemisphere.

#11

Front (Question)

Meninges

Back (Answer)

Special membranes found in the dorsal cavity that surround the brain and spinal cord.

#12

Front (Question)

Brain ventricle

Back (Answer)

Ventricle refers to hollow chamber. There are 4 hollow spaces in the brains that contain CSF (cerebrospinal fluid).

#13

Front (Question)

Longitudinal fissure separates the___________.

Back (Answer)

The left cerebral hemisphere and the right cerebral hemisphere.

#14

Front (Question)

The cerebral cortex in the brain is found on _______________ portion of the cerebrum.

Back (Answer)

The outer portion.

#15

Front (Question)

Areas (masses) of grey matter found in the deeper portion of the cerebrum are called_____________.

Back (Answer)

Cerebral nuclei

#16

Front (Question)

Areas (masses) of grey matter found in the deeper portion of the cerebrum are called_____________.

Back (Answer)

Cerebral nuclei

#17

Front (Question)

Cerebral nuclei are __________________ centers.

Back (Answer)

Processing (integration)

#18

Front (Question)

The inner portion of the brain contains ______________ and ____________.

Back (Answer)

White matter and gray matter (called nuclei).

#19

Front (Question)

What part of the brain is known as the “little cerebrum”?

Back (Answer)

Cerebellum

#20

Front (Question)

Arrange the following in order from superior to inferior. Medulla oblongata, Midbrain, Pons

Back (Answer)

Midbrain, Pons, Medulla oblongata

#21

Front (Question)

A stroke is more likely to be fatal if it occurs in the ________________ part of the brain.

Back (Answer)

Injuries and strokes occurring in the brainstem are most likely to be fatal due to the major vital centers located here. Respiratory, cardiac and blood pressure.

#22

Front (Question)

Where does the brainstem connect to the spinal cord?

Back (Answer)

At the foramen magnum of the skull.

#23

Front (Question)

What separates the arachnoid mater from the pia mater?

Back (Answer)

The subarachnoid space which contains the CSF.

#24

Front (Question)

The pia mater holds tight (hugs) to the:

Back (Answer)

Brain and spinal cord.
