PSYB65H3 Chapter Notes - Chapter 2: Neuroglia, Phenotypic Plasticity, Midbrain Tectum
Document Summary
Plastic patterns of neural organization: brain is plastic: neural tissue has the capacity to adapt to the world by changing how its functions are organized. The cns includes the brain and the spinal cord, the structures at the core of the nervous system that mediate behavior. The somatic nervous system (sns), all the spinal and cranial nerves carrying sensory information to the cns from the muscles, joints, skin, also transmits outgoing motor instructions that produce movement. The autonomic nervous system (ans) balances the bodys internal organs to. Cerebral security: behind the skull, the first layer is the meninges: three layers of protective tissue (dura mater, archnoid and piemata) that encase the brain and spinal cord. Dura mata --is a tough double layer of fibrous tissue that encloses the brain and spinal cord in a kind of loose stack. Archnoid--a very thin sheet of delicate connective tissue that follows the brain contours.
