Brain structure and functions worksheet

The forebrain has two major parts called the diencephalon and the telencephalon. Interestingly, each of our various body parts has a unique portion of the primary motor cortex devoted to it see Figure 6.

License: Other. When a sensory message meets certain parameters, the spinal cord initiates an automatic reflex. What we do know is that the left hemisphere controls the right half of the body, and the right hemisphere controls the left half of the body.

The notion of functions being products of brain areas or centers is left over from the days when most evidence about brain function was based on the effects of brain lesions localized to specific areas. Figure 4. On September 13, , Gage age 25 was working as a railroad foreman in Vermont. Sensory nerves bring messages in; motor nerves send messages out to the muscles and organs. As a result, she has great difficulty moving her left leg. Therefore, the lower on the spine damage is, the fewer functions an injured individual loses. Output from the cerebrum passes through the diencephalon. It includes neurons that we use to process data and controls our coordination, balance, and equilibrium. The corpus callosum allows the two hemispheres to communicate with each other and allows for information being processed on one side of the brain to be shared with the other side. While this is an effective treatment option, it results in individuals who have split brains. The occipital lobe is located at the very back of the brain, and contains the primary visual cortex, which is responsible for interpreting incoming visual information. This part of the brain controls body functions, which includes muscle movement, sensory impulses and touch sensation.

Dopamine receptors are either excitatory D1-type receptors or inhibitory D2-type receptors. Therefore, the lower on the spine damage is, the fewer functions an injured individual loses.

The cerebrum also controls organization, planning, intelligence level, personality as well as the way we think, process and understand language. The auditory cortex, the main area responsible for processing auditory information, is located within the temporal lobe.

As shown in this video, the direct pathway is the shorter pathway through the system that results in increased activity in the cerebral cortex and increased motor activity. Many of the higher neurological functions, such as memory, emotion, and consciousness, are the result of cerebral function. These regions assists in maintaining balance and equilibrium, movement coordination, and the conduction of sensory information. Input to the basal nuclei is from the cerebral cortex, which is an excitatory connection releasing glutamate as a neurotransmitter. In the opposite direction, the spinal cord ends just below the ribs—contrary to what we might expect, it does not extend all the way to the base of the spine. The basal nuclei are also referred to as the basal ganglia, although that is potentially confusing because the term ganglia is typically used for peripheral structures. The folding of the cortex maximizes the amount of gray matter in the cranial cavity. Many of his friends described him as no longer being himself. It controls how we perceive what we see and how we recognize colors. It includes neurons that we use to process data and controls our coordination, balance, and equilibrium. Hypothalamus The hypothalamus is part of the limbic system. Authored by: OpenStax College.

The midbrain, also called the mesencephalon, connects the hindbrain and the forebrain.
