Study Notes
- The speaker is introducing a lecture on formercology, specifically on neurohemoral transmission.
- Neurohemoral transmission involves the transmission of signals between neurons using chemical messengers.
- In a demonstration, the speaker touches a hot object, and the brain sends a signal to move the hand away to prevent damage.
- Neurohemoral transmission involves two neurons communicating via chemicals, ultimately affecting muscles, organs, and tissues.
- The process involves dendrites receiving signals, axons transmitting signals, synaptic knobs helping in transmission, and synaptic clefts for signal exchange.
- Neurons have structures like smooth endoplasmic reticulum and microtubules for functions like protein synthesis and transport.
- Neurotransmitters are chemicals that aid in signal transmission, while receptors on the receiving end help in recognizing and responding to these chemical messages.
- The process involves the formation of synaptic junctions between neurons for signal transfer.
- The concept also includes details on neural structures like axon terminals, covering sheets, and action terminals.
- The gap between neurons where signal transmission occurs is known as the synaptic knob, and the end of an axon is called the axonal terminal.
This quiz provides an overview of neurohemoral transmission in the nervous system, focusing on the communication between neurons using chemical messengers. Topics covered include signal transmission pathways, neuron structures, neurotransmitters, and synaptic junctions.
