Document Summary
The brain receives sensory (afferent) impulses from the peripheral and cranial nerves. The brain integrates the information received from sensory receptors and interprets information about the environment. Following integration, the brain initiates motor (efferent) impulses that innervate effector organs in response to the initial stimuli. Certain portions of the brain like the hypothalamus and pituitary gland are part of the endocrine system. These contain specialized nervous tissues that produce and release hormones into the bloodstream. Together, the brain and endocrine system maintain homeostasis and regulate bodily functions. Cranial fossae, meninges, dural sinuses and arterial supply. The anterior cranial fossa accommodates the frontal lobes of the brain and is located anterior to the lesser wing of the sphenoid bone. Cranial fossae the middle cranial fossa is located posterior to the lesser wing of the sphenoid and anterior to the petrous portion of the temporal bone. The middle cranial fossa houses the temporal lobes of the brain.
