Autonomic Nervous System Drugs Flashcards
It plays an important role in the human body, controlling many of the body’s automatic processes.
Autonomic Nervous System (ANS)
It is the master controller of most activities in the body.
Nervous System
Nervous System has two main parts:
Central Nervous System
Peripheral Nervous System
Central Nervous System contains -
Brain and Spinal Cord
Peripheral Nervous System contains -
Autonomic Nervous System and Somatic Nervous System
What is the difference between Afferent and Efferent?
Afferent neurons carry information from sensory receptors of the skin and other organs to the central nervous system (Outside to in). While Efferent neurons carry motor information away from the central nervous system to the muscles and glands of the body (In to outside).
Autonomic Nervous System (ANS) is divided into 2 parts;
Sympathetic (Adrenergic) and Parasympathetic (Cholinergic)
All preganglionic neurotransmitters are actually_______.
Acetylcholine (ACH)
What are the difference between somatic and autonomic nervous system?
Somatic Nervous System consists of nerves that go to the skin and muscles and is involved in conscious activities. While Autonomic Nervous System consists of nerves that connect the CNS to the visceral organs such as the heart, stomach, and intestines. It mediates unconscious activities.
What are the 5 steps of Synaptic Transmission?
Step 1: Synthesis
Step 2: Storage
Step 3: Release of the neurotransmitter
Step 4: Action at the receptor site
Step 5: Termination of the transmission
3 ways:
5a: Re-uptake
5b: Enzymatic degradation
5c: Diffusion away
What are the two terminals in Synaptic Transmission?
Presynaptic Nerve Terminal and Postsynaptic Cell
Sympathetic only means_____.
Feeling together
The receptor organ cells in Sympathetic Nervous System are_________.
Alpha and Beta (Alpha 1 and 2 , Beta 1 and 2)
The terminal neurotransmitter of Sympathetic Nervous System
Norepinephrine
It means rest and digest.
Parasympathetic Nervous System
