7.01: Nervous and Endocrine Systems
1. What are the 4 lobes of the brain? Know where they are located if given a picture of the brain. - Temporal Lobe The temporal lobe is located on the side of each hemisphere, behind the ears. It is associated with speech, hearing, and memory skills. It houses the hippocampus (the area of the brain associated with memory) and contains the auditory centers responsible for hearing. Occipital Lobe The occipital lobe is found at the back of each hemisphere. Although it is located farthest away from the eyes, this lobe of the brain deals with visual interpretation. It receives measurements taken from the eyes' lenses and processes those signals into information about what the eyes are seeing. Parietal Lobe The parietal lobe is the middle region of each hemisphere, lying beneath the crown of the skull. It is the cognition part of the brain. The parietal lobe works by instinct as it receives signals of different sensations—such as pain, warmth, cold, pressure, and movement—from the skin. Frontal Lobe The frontal lobe is the front part of each hemisphere. This lobe processes information from all other areas of the brain. This area of the brain is our emotional control center and the area we use for problem solving, judgment, impulse control, and social and sexual behavior. The frontal lobe in a human does not fully develop until around 25 years of age.
2. Where is the cerebellum located in the brain? What is its’ function? - Cerebellum The cerebellum is located behind the hindbrain and is tucked partially beneath the cerebrum. It is responsible for the coordination of movement. It receives sensory information from nerves near joints and muscles as well as information from visual and auditory systems. It uses this information to provide unconscious coordination of movement and balance. Hand-eye coordination is one example of the cerebellum's function.
