What is the Difference between a weak stimulus and intense stimulus?
The FREQUENCY of action potentials that are conducted into the central nervous system serves as the code for the strength of the stimulus. This frequency code is needed because the amplitude of action potentials is constatnt (all or none). Acting through changes in action potential frequency, tonic receptors thus provide information about the relative intensity of a stimulus.
How do you determine you have a bad central nervous system?
i don't know that much
The idea that an emotion-arousing stimulus is simultaneously routed to the cortex and to the sympathetic nervous system is central to the?
Cannon-Bard theory
What is a somatic reflex and how does it occur through the CNS?
A somatic reflex is where the body responds to stimulus. The message from the stimulus is sent through the central nervous system via the spine, and from there it travels to the brain.
The simplest pathway able to receive a stimulus enter the central nervous system for immediate interpretation and produce a response is known as a?
beatroot
What is the system that reacts to a stimulus?
Nervous system
What drug category is Dexedrine classified as?
Dexedrine is classified as a central nervous system stimulant. Central nervous system stimulants vary in strength, but all cause an increase in wakefulness and concentration; they are used for treating ADHD and narcolepsy.
The cranial and spinal nerves form what nervous system?
the peripheral nervous system
What structure detects the stimulus in the reflex action?
The stimulus is detected by temperature or pain receptors in the skin. These generate impulses in sensory neurons. The impulses enter the CNS ( Central nervous system ) through a part of the spinal nerve called the Dorsal root.
Is the brain part of the Central Nervous System or the Peripheral Nervous System?
Central nervous system. In fact, the brain is the CENTER of the central nervous system.
What are the major components of the central nervous system and the peripheral nervous system?
CNS = central nervous system (brain and spinal cord)PNS = peripheral nervous system (that part of the nervous system that extends outside the central nervous system)
The central nervous system in vertebrates consists of the what and the spinal cord?
The central nervous system
