Study Notes
Reflex Arc Functionality
- The integrating center processes sensory information and determines the appropriate motor response in a reflex arc.
- Monosynaptic reflex arcs involve direct communication between the sensory neuron and motor neuron, characterized by only one synapse in the central nervous system (CNS).
- Polysynaptic reflex arcs contain more than two types of neurons and involve at least one interneuron, allowing for multiple synapses within the CNS.
Reflex Types
- The Stretch Reflex primarily involves the muscle spindle and is characterized by the contraction of skeletal muscle in response to stretching.
- The Golgi Tendon Reflex also qualifies as a polysynaptic reflex, which helps prevent muscle damage from excessive force.
Sensory Organ & Neurotransmitters
- Muscle spindles are the sense organs involved in the Stretch Reflex, detecting changes in muscle length.
- The neurotransmitter typically utilized for transmitting impulses from the sense organ to the CNS in the Stretch Reflex is glutamate.
Distinguishing Features
- A distinguishing feature of a polysynaptic reflex arc is the presence of interneurons, allowing the reflex to involve more complex pathways and integrations.
- Monosynaptic reflex arcs are characterized by having only one synapse between the sensory and motor neurons, resulting in a quick response.
Roles of Components
- The primary role of the muscle spindle in the Stretch Reflex is to detect stretch and relay information about muscle length to the CNS, facilitating an appropriate response.
