Overview of Nervous System Flashcards
Autonomic Nervous sytem
Controls involuntry responses by influsing organs, glands, and smooth muscle
Sympatehic Division
Parasympathetic division
Adrenergic Receptors
Cholingeric Receptors
Function of CNS
Functions of the PNS
Recognize changes in the internal and external environment
Relies on receptors that respond to different sensory modalities
React to environmental changes by producing an action or response
Relies on somatic and autonomic motor neurons to carry out action or response
Structure of the PNS
Peripheral nervous system
Consists of:
Nerves that carry messages to the CNS (sensory) about environment
Nerves that carry messages from the CNS (motor) to carry out responses
Somatic component – voluntary
Autonomic component - involuntary
Neurons of the PNS: Sensory
Neurons of the PNS: Motor
Structures of the ANS: Two divisions
Sympathetic
Parasympathetic
Functions of ANS
Function of the ANS: Homeostasis
Anatomy of The ANS: Two neuron and ganglion
The primary ANS neurotransmitters
- Norephinephrine
- Acetylcholine
ANS Drugs
Receptors of the ANS
CHolinergric Receptor
For the Parasymthic nervous system
