Study Notes
Neurons and Nerve Pathways
- Neurons are the fundamental unit of nerve pathways, responsible for sending messages throughout the body.
- Dendrites are the parts of the neuron that receive input from other neurons.
Axon and Synapses
- Synaptic vesicles are the tiny-looking bubbles at the end of an axon, containing neurotransmitters that facilitate communication between neurons.
Supportive Cells
- Glial cells support neurons by insulating them, synchronizing neuronal activity, and removing waste products.
Impulse Transmission
- Myelin sheaths speed up the transmission of impulses along an axon, allowing for faster communication between neurons.
Signal Conversion
- The process of converting physical or chemical energy into electrochemical messages in neurons is known as transduction.
Action Potential
- The tiny electric current generated when positive sodium ions rush inside the axon is called an action potential.
Types of Neurons
- Afferent neurons carry sensory information from the senses to the spinal cord, facilitating the sensation process.
Autonomic Nervous System
- The autonomic nervous system regulates involuntary bodily functions, such as heart rate, digestion, and respiratory rate.
Sympathetic Division
- The sympathetic division of the autonomic nervous system prepares the body for action, especially in response to threatening or challenging stimuli.
Central Nervous System
- The central nervous system comprises the brain and spinal cord, serving as the main control center for processing information.
Role of Interneurons
- Interneurons primarily facilitate communication between sensory and motor neurons, playing a crucial role in reflexes and processing information.
