Autonomic Nervous System (ANS)
This regulates the activity of smooth muscle, cardiac muscle and glands
Autonomic sensory neurons, Integrating Centers in the CNS and Autonomic motor neurons
Structurally the ANS includes what three parts?
Limbic System and other regions of the cerebrum
The hypothalamus and medulla oblongata receive input from where?
Somatic nervous system
1. This system's sensory neurons receive input from receptors of the special senses that are perceived consciously
2. This system's motor neurons innervate skeletal muscle to produce conscious, voluntary movement. The effect is always excitation
Autonomic nervous system
1. This system's sensory neurons are associated with interoceptors in viscera. These activities usually lie beyond conscious control and not consciously perceived.
2. Motor Neurons regulate visceral activities by either increasing (exciting) or decreasing (inhibiting) ongoing activities of cardiac muscle, smooth muscle or glands. Can not be consciously altered or suppressed.
Two efferent neurons of this type synapse from CNS to glanglion, and then glanglion to visceral effector.
Nerves, ganglia and plexuses
Autonomic nervous system consists of visceral efferent neurons organized into what?
The first of two autonomic efferent neurons (with myelinated axons) extend from CNS to ganglion is called what?
The second of two autonomic efferent neurons (with UNmyelinated axons) lies entirely outside the CNS and extends directly to the effector (muscle or gland)
Sympathetic trunk ganglia (on both sides of spinal column), prevertebral ganglia (anterior to spinal column) and parasympathetic terminal ganglia (near or inside visceral effectors)
Autonomic ganglia are classified as what and located where?
receptor, afferent neuron, association neuron, visceral efferent preganglionic neuron, Visceral efferent postganglionic neuron, and visceral effector
Name the six components of a Visceral autonomic reflex arc
To convey a motor impulse from the CNS to the autonomic ganglion
The role of the preganglionic neuron is what?
These produce NE and their effects are longer lasting and more widespread. Most sympathetic postganglionic neurons are these.
Alpha and Beta Receptors
NE interacts with these two types of adrenergic receptors on visceral effectors.
Energy conservation and restoration such as salivation, lacrimation, urination, digestion and defecation.
This controls and integrates with the autonomic nervous system. It is connected to both the sympathetic and parasympathetic divisions
This is a process in which people learn to monitor visceral functions and to control them consciously. It can be used to control heart rate, ease migraine headaches and make childbirth easier.
This is a higher consciousness achieved through a fully rested and relaxed body and a fully awake and relaxed mind.
