Parts of The Brain The frontal lobe – The frontal lobe – This part of the brain is the primary command and control center of your brain. It is responsible for reasoning and problem solving along with judgment and impulses. It can also be involved in motor control and memory.

The cerebrum is the most highly developed part of the human brain. It is here that things like perception, imagination, thought, judgment, and decision occur. The cerebrum is the most highly developed part of the human brain. It is here that things like perception, imagination, thought, judgment, and decision occur. Brain Stem: Brain Stem: The brainstem is the region of the brain that connects the cerebrum with the spinal cord. Motor and sensory neurons travel through the brainstem allowing for the relay of signals between the brain and the spinal cord.

The Spinal Cord The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. A pair of spinal nerves leaves each segment of the spinal cord. A pair of spinal nerves leaves each segment of the spinal cord. The length of the spinal cord is about 45 cm in men and 43 cm in women. The length of the spinal cord is about 45 cm in men and 43 cm in women.

Parts of The Spinal Cord Cervical Nerve branches off from the nerves in the spinal cord. The cervical nerves are responsible for relaying messages and ensuring functioning to different body parts.

C1-C8 controls the head, diaphragm, upper body muscles, wrist extensors, triceps, and hand. C1-C8 controls the head, diaphragm, upper body muscles, wrist extensors, triceps, and hand. Thoracic spine refers to the upper- and middle-back. Thoracic spine refers to the upper- and middle-back. T1-T12 controls the chest and abdomen muscles. T1-T12 controls the chest and abdomen muscles. Thoracic spine is built for stability. This stability plays an important role in holding the body upright and providing protection for the vital organs in the chest.

Parts of The Spinal Cord Lumbar spine has no spinal cord and is made up of a large amount of space for the nerve roots. Lumbar spine has no spinal cord and is made up of a large amount of space for the nerve roots. L1-L5 controls the leg muscles. L1-L5 controls the leg muscles. Sacral nerve is located at the bottom of the spine. Sacral nerve is located at the bottom of the spine. S1-S5 control the bladder and bowels. S1-S5 control the bladder and bowels.
