This is called the “motor unit” and can vary from a handful of muscle fibers per motor neuron in muscles of very fine control (such as eye muscles) up to several thousands (as in the gluteal muscles). The autonomic nervous system consists of 2 main divisions, the sympathetic and the parasympathetic nervous systems.
Which part of the nervous system contains the autonomic system?
The hypothalamus, just above the brain stem, acts as an integrator for autonomic functions, receiving autonomic regulatory input from the limbic system. The autonomic nervous system has three branches: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.
What are the 2 parts to the autonomic nervous system?
The autonomic nervous system has two main divisions:
- Sympathetic.
- Parasympathetic.
Where is the peripheral nervous system located?
Peripheral nerves reside outside your brain and spinal cord. They relay information between your brain and the rest of your body. The peripheral nervous system is divided into two main parts: Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands.
What are the similarities and differences between the somatic nervous system and the autonomic nervous system?
The somatic nervous system has sensory and motor pathways, whereas the autonomic nervous system only has motor pathways. The autonomic nervous system controls internal organs and glands, while the somatic nervous system controls muscles and movement.
What is another name for the autonomic nervous system?
The autonomic nervous system (ANS) is also called the vegetative nervous system. It controls the involuntary functions and influences the activity of internal organs.
