- Autonomic (involuntary)
What are the 2 divisions of the Autonomic Nervous System?
- Sympathetic
- Parasympathetic
What do Afferent Neurones do?
Afferent neurones carry information from sensory receptors of the skin and other organs to the central nervous system
What do Efferent Neurones do?
Efferent neurones carry motor information away from the central nervous system to the muscles and glands of the body
What is the Coronal Plane?
- Frontal Plane
- Separates front and back
What is the Transverse Plane?
- Horizontal Plane
- Separates up and down
What is Sagittal Plane?
- Midline Plane
- Separates left and right
What is Parasagittal Plane?
- Midline Plane but not in the middle,
- Separates left and right but not in equal parts
