- The nervous system
- The nervous system- coordinates the actions of the body through electrical impulses
- The peripheral nervous system consists of the neurones that carry impulses into and out of the CNS . The peripheral nervous system contains sensory and motor neurones.
- Sensory neurones- carry impulses from receptors to CNS
- Motor neurones carry impulses from the CNS to effector cells
- SOMATIC- impulse carried from CNS to skeletal muscles under control
- AUTONOMIC- from CNS to cardiac muscle (not under voluntary control)
- SOMATIC- impulse carried from CNS to skeletal muscles under control
- The CNS consists of the brain and spinal chord. Made up of grey matter ( non myelinated nerve cells) and white matter (myelinated nerve cells)
