CONTENTSThe most important parts of the brain are: Cerebrum Cerebellum Brain Stem Pituitary gland Hypothalamus
The biggest part: the Cerebrum It has two halves or hemispheres: the right hemisphere and the left hemisphere. It controls: ** voluntary movement ** speech ** intelligence ** memory ** emotion and **sensory processing.
The two halves of the cerebrum: Each hemisphere is specialized in different functions. The left hemisphere is generally related to the right side of the body and vice versa.• The left hemisphere controls --> language, maths and logic....• The right hemisphere controls --> spatial orientation, face recognition, body image, ability to appreciate art and music...
The cerebellumIt is at the back of the brain.It controls: balance, movement, coordination andmuscle-tone.
Brain StemIt sits beneath the cerebrum and in front ofthe cerebellum.It connects the rest of the brain to the spinalcord.The brain stem is in charge of all thefunctions your body needs to stay alive, likebreathing air, digesting food, and circulatingblood.
Pituitary glandThe pituitary gland is quite small.It produces and releases hormones intoyour body.These hormones are involved in regulatinggrowth, puberty, metabolism, water andmineral balance, the body’s response tostress,etc...
HypothalamusHypothalamus controls functions likethirst, appetite and sleep patterns.It also regulates the release of hormonesof the pituitary gland,and controls the temperature of yourbody.
NervesThe brain needs thespinal cord (with a longbundle of nerves insideit).The nervous system(spinal cord and nerves)is the one that letsmessages flow backand forth between thebrain and body.
