Document Summary
Identify the gross anatomy of the brain and spinal cord. Identify the arteries comprising the cerebral arterial circle: explain the structural and functional divisions of the nervous system, describe the structure and function of the cranial meninges, understand the difference between grey and white matter. Functions of nervous system: sensory input (afferent signals to cns, integration (in cns, motor output (efferent signals from cns, talking, breathing. Integration between feeling pain and contracting is done within central nervous system: 2 main division of cns is brain and spinal cord and pns is outside cns. Pns is divided into sensory and somatic. Motor is divided into autonomic and somatic. Vertebral foramen= big one behind body of vertebrae. Thin spinal cord in cervical= circular vertebrae foramen. Also cerebrospinal fluid which is made in the ventricles. Cerebrospinal fluid sits in sub arachnoid space= below arachnoid layer> arachnoid layer looks spider like.
