Anatomy & Physiology Nervous #15
Which structure of the central nervous system is responsible for coordinating and enabling bodily movements and the sense of smell?
The cerebrum is the largest part of the brain that coordinates and enables bodily movement, communication, judgement, language, learning, memory, and sensory perception including the senses of hearing, seeing. smelling, and tasting.
The cerebellum, or the small brain, controls and manages bodily movement in terms of motor control, balance, equilibrium, fine and gross motor coordination, and to a lesser extent plays a role in attention span and speech. It does not control both coordinating or enabling body movement in addition to the sense of smell.
- Brain stem
The brain stem controls the flow of messages between the brain and the rest of the body. It also controls basic bodily functions including blood pressure, breathing, consciousness, heart rate, and swallowing in addition to sleep and wake patterns. It does not control both coordinating or enabling body movement in addition to the sense of smell.
- Medulla oblongata
The medulla oblongata is one of the structures of the brain stem. It is the control center for most basic vital signs and functions including breathing, cardiac functioning, coughing, sneezing, swallowing, and vomiting.
The nervous system has two primary branches, the central nervous system (CNS) and the peripheral nervous system (PNS).
The CNS contains the brain and the spinal cord. The three primary brain structures are the cerebrum, cerebellum, and the brain stem. The cerebrum is responsible for coordinating and enabling bodily movements and the sense of smell.
