The brain weighs about three pounds (Fleischman, 2002, p.27). There are four different sections of the brain. The different sections are cerebrum, cerebellum, diencephalon, and the brain stem. The cerebrum is the largest part of the brain (Brain, 2015, p.1). In a brain, there are many neurons. Neurons are a long skinny cell with a tangle of receivers at one end. (Fleischman, 2002, p.33) The receivers are called dendrites. …show more content…
The cerebrum has lobes, these lobes are called frontal, temporal, parietal, and occupational lobes (Kinser, 2000, p.1). “The frontal lobe is associated with reasoning, planning, parts of speech, movements, emotions, and problem solving” (Kinser, 2000, p.1). The occipital lobe controls visual processing. This helps you process what you see, like when you see your name in print. The temporal lobe is involved with perception and recognition of auditory stimuli, memory, and speech. When the brain is receiving information correctly, it allows people to properly interpret and respond to their …show more content…
The midbrain controls the auditory reflex centers, like moving head to hear sound better. In the pons there are nuclei. The nuclei relay sensory impulses from peripheral nerves to higher brain centers. Nuclei control vital visceral activities like the cardiac center, vasomotor, and respiratory centers. It also regulates the rate and depth of breathing. All nerve fibers connected to the brain and spine must pass through the medulla oblongata . It's covered by white matter. The brain also has layers protect the brain. The layers are bones of the skull, meninges, a series of sturdy membranes that surround the brain and spinal cord, and fluid (Brain, 2015, p.1). The brainstem controls heart rate, breathing, sleeping, and eating (Boundless, 2015, p.1). The brain stem connects the brain with the spinal cord (Boundless, 2015, p.1). In order to get the right messages sent to the brain for movement, the spinal cord needs to be functioning properly. When people are paralyzed, the spinal cord isn't getting messages to the brain correctly for
