10 Questions
What is the primary function of transmission in the nervous system?
To send impulses from the site of transduction to the brain
What is the first stage of the transmission process?
From the site of transduction to the dorsal horn of the spinal cord
What is the final stage of the transmission process?
Through connections between the thalamus, cortex, and higher levels of the brain
How many stages are involved in the transmission process?
3
Where do the impulses ultimately end up after transmission?
The brain
What is the primary location where impulses are transmitted from the transduction site?
Dorsal horn of the spinal cord
During the transmission process, what is the intermediate stop for impulses after leaving the spinal cord?
Thalamus
What is the ultimate destination of the impulses after transmission through the thalamus?
Cerebral cortex
What is the purpose of the connections between the thalamus, cortex, and higher levels of the brain?
To facilitate higher-level sensory processing and integration
Which stage of the transmission process involves the transmission of impulses from the spinal cord to the brain stem?
Second stage
Study Notes
Transmission of Impulses
- Impulses are sent to the dorsal horn of the spinal cord through transmission
- Transmission occurs in 3 stages
Stage 1: Signal Propagation
- Signals are transmitted from the site of transduction to the dorsal horn of the spinal cord
Stage 2: Signal Relaying
- Signals are transmitted from the spinal cord to the brain stem
Stage 3: Higher-Level Processing
- Signals are transmitted through connections between the thalamus, cortex, and higher levels of the brain
