The Human Brain Is Composed Of Many Parts.

• We will build it from the bottom up.

The Base Of The Brain

• Takes care of basic functions and gross motor
  movement.

The Cerebellum

• The trilobed structure of the brain, lying
  posterior to the pons and medulla oblongata and
  inferior to the occipital lobes of the cerebral
  hemispheres is responsible for the regulation and
  coordination of complex voluntary muscular
  movement as well as posture and balance.

9
The Diencephalon

• The Thalamus a large ovoid mass of gray matter
  situated in the posterior part of the forebrain
  relays sensory impulses to the cerebral cortex.
• The Diencephalon located in the posterior part
  of the forebrain connects the midbrain with the
  cerebral hemispheres. It encloses the third
  ventricle, and contains the thalamus and
  hypothalamus. This region is also called the
  betweenbrain, interbrain, or thalamencephalon.

11
The Hypothalamus

• This part of the brain lies below the thalamus,
  forming the major portion of the ventral region
  of the diencephalon. It functions to regulate
  body temperature, certain metabolic processes,
  and other autonomic activities.

13
Hippocampus

• Is a ridge in the floor of each lateral ventricle
  of the brain that consists mainly of gray matter
  and has a central role in memory processes.

14

15
The Lateral Ventricle

• Is an internal cavity in each cerebral hemisphere
  that consists of a central body and three cornua
  including an anterior one curving forward and
  outward, a posterior one curving backward, and an
  inferior one curving downward.

16

17
The Caudate Nucleus

• Is an elongated, curved mass of gray matter
  consisting of three portions an anterior, thick
  portion that projects into the anterior horn of
  the lateral ventricle a portion extending along
  the floor of the body of the lateral ventricle
  and an elongated, thin portion that curves
  downward and backward in the temporal lobes to
  the wall of the lateral ventricle. It is also
  called caudatum or the Caudate.

19
The Putamen

• Is the outer, larger, and darker gray of the
  three portions into which the lentiform nucleus
  of the brain is divided.

21
The Amygdala

• Is an almond-shaped mass of gray matter in the
  anterior portion of the temporal lobe. It is also
  called the amygdaloid nucleus.

22

23
The White Matter

• Is Myelinated fiber. This region covers the
  parts of the brain which performs basic functions
  and is under the lobes or gray matter.

25
The Brain Lobes

• This is the area of the brain which comprises the
  thinking portion. It is considered the higher
  cortical region of the cerebral cortex.
