Brain Structure and Function
Transcript of Brain Structure and Function
Controls movement and plans behavior
controls hearing and enables recognition of objects and faces
Involved with the control of involuntary functions such as breathing, muscle tone, and blood circulation
includes two hemispheres made up of cerebral cortex and basal nuclei, which control cognitive and motor functions
consists of thalmus and hypothalmus, which both deal with sensory motor functions
Produces melatonin, which is a hormone that affects the modulation of sleep patterns
vital to the formation of memories and other higher functions
consists of four cavities that contain cerebrospinal fluid, which cushions the brain inside the skull and protects the spinal cord

Function: controls bodily sensations
Sensory and Motor Area
sensory-receives messages from sense organs (eyes, nose, tongue, or ears)
motor-controls voluntary muscle movements
Pons and Midbrain
pons- controls sleep and arousal
midbrain-controls sensory processes
ascending-responsible for the sleep wake cycle
descending- regulates motor movement
Located in the back region of the brain where images of the eyes are processed.
relays sensory information to the cerebral cortex
Function: Anterior and posterior sections secrete hormones i.e. growth hormone (anterior) and oxytocin (posterior)
Function: Organizes motor behavior

Bundle of neurons that connects the left and right hemisphere and allows for interhemispheric communication
Located in the back of the brain and controls motor functions
Sulci and Gyri
The folds and grooves of the brain that increase its surface area and divide each hemisphere into four lobes. The gyri are the ridges and the Sulci are the grooves.
Connects the nervous and endocrine systems through the pituitary gland. Controls body temperature.
Meninges:the three connective tissue layers that cover the brain. Skull:bone structure of the head that is composed of two parts; the cranium and the mandible. Creates a protective cavity for the brain
system of brain structures which include the hippocampus, amygdala, and olfactory bulbs.
