In addition, the brain stem coordinates the fine movement of the face and limbs. The spinal cord's nerve tissues are approximately 45 centimeters long, and nearly 2 centimeters bulk, and they conform the peripheral nervous system. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS. The brain and spinal cord are the two main structures of the central nervous system.

Pelvis/Thigh Origin/Insertion. However, the effects of reducing sedentary behaviour duration on cognitive function, brain function, and structure remain poorly understood. The limbic system, a region under the cortex, processes our emotions and drives. These parts are shown in Fig. 3. Fore Brain 2. Plants and animals have different tissues. The midbrain consists of various cranial nerve nuclei, tectum, tegmentum, colliculi, and crura Celebi. It functions across the control of motor skills, higher level cognition, and expressive language. 5. The functions of the brain are varied, and include: thinking, perception (sensing), emotion, signaling, and many of our physical functions.
