9 important questions on Zenuwstelsel en Zintuigen - Phys : Nerve cells and electrical signalling
What are the somatic senses and the special senses?
What are the two cell classes of the nervous system?
Glial cells and neurons. Neurons are exitable cells that are able to produce action potentials and Glial cells are 90% of the total nervoussystem cells and provide support to the neurons (structural and metabolic).
What do neurons consist of?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What are the parts of an axon?
Difference presynaptic cell and postsynaptic cell?
What are the three kinds of (ion)channels found in neurons?
What are the three functional classes of neurons?
Efferent neurons- transmit info from the CNS to effector organs (including the motor neurons extending to skeletal muscle and neurons of the autonomic nervous system). (cell body within the CNS)
Afferent neurons- transmit sensory info from sensory receptors or viceral receptors to the CNS. (Cell body outside the CNS)
Interneurons account for 99% of all neurons in the body all in the CNS. they preform the functions of the CNS.
What are the 5 Glia cell types?
How is Alzheimer's disease caused?
