Transcript of Human brain

To conclude we can say that the brain is the center of the body. Everything you do, feel, think and say depends on your brain. It is divided in different parts that control several functions, like movement, speech, storing memories, and balance. Damaging a region can affect the functions it controls,like the loss of movement, difficulty speaking, or losing coordination. Finally, without the brain we could not exist as we are just because it controls everything, and the body could not work the same.
Mastering Biology
The brain is one of the most important organs of the human body. It controls all the different body parts such as the arms and the legs. It reacts in a different way in every different situation by sending instructions to each body part to move in a certain way. This instructions are transported by neurons that are all around the body.
Brain Stem
Controls reflexes and involuntary movements
It is divided into:
Cerebrum and cerebellum
Thalamus and Hypothalamus
Skull and Cerebrospinal fluid
It is the highest part of the brain stem, it adjusts the sensibility of your eyes (with light) and your ears (with sound).

It is like a road that let messages travel between the brain and spinal cord.
Medulla Oblongata:
Reticular Formation:
It is part of the medulla Oblongata, reticular formation is a filter for sensory input, analyzes the constant information, sensory information, and passes out stimuli that does not require response. This helps to prevent the brain from having to react many times from familiar stimuli.

Cerebrospinal fluid: protect the brain and help to cushion in case of a blow

Skull: protect the brain and organs senses like smell, audition and vision

Cerebrum: is in charge to control language, memory sensation and the decisions that you make

Cerebellum: is in charge to coordination also control balance and muscular movement

Thalamus: control the sensory information and motor response for the cerebrum

Hypothalamus: is in charge to control sex drive, pleasure, pain, hunger and thirst, blood pressure and the temperature of the body

It is located in the lower part of the brain stem, it controls heart rate, and transports information between the spinal cord, and other parts of the brain.
Parietal Lobe:

Process information about touch and self-awareness

Frontal Lobe:
Process voluntary muscle movement and organizes and plans future behavior

Temporal Lobe:
Process the hearing and the smelling information and its important in memory and emotion

Occipital Lobe:
Process the sight.
