Motor sensory brain
Nettet9. nov. 2024 · About fifteen percent (15%) of the daily cardiac output is utilized by the brain. Owing to the high oxygen and nutrient demand of the organ, it is supplied by two arterial systems: The anterior circuit is supplied by the internal carotid arteries. The posterior circuit is supplied by the vertebrobasilar system. NettetThe cranial nerves connect the head and neck directly to the brain, but the spinal cord receives sensory input and sends motor commands out to the body through the spinal nerves. Whereas the brain develops into a complex series of nuclei and fiber tracts, the spinal cord remains relatively simple in its configuration (Figure 16.12).
