reflexes Flashcards
unconscious responses, which means they are automatic and do not require the brain to create the action
REFLEXES
contains only one space where information in the spinal cord travels between two nerve cells, called neurons.
Simple reflex
The space between two neurons
synapse
Four Parts of Monosynaptic Simple Reflex
Sensor, Sensory Neuron, Motor Neuron and Muscle
which senses what is happening to the body
Sensor
carry that information to the spinal cord
Sensory Neuron
transmit information away from the spinal cord
Motor Neuron
creates an action in the Monosynaptic Simple Reflex
Muscle
In order for reflexes to work, this messages need to move around the body and they travel along the neurons and send messages. what is this messages called?
Action Potential
three different parts that allows to be sensed, to travel, and to move to another neuron or muscle
Dendrites, Axon and Nerve Endings
receive information from the sensor or other neurons
Dendrites
transmits information to different neurons.
Axon
send messages to your brain when you feel sensations such as heat, cold, and pain
Nerve Ending
rapid, predictable, involuntary motor response to stimuli
Reflexes
Reflexes are mediated over neutral pathways called
Reflex arcs
5 ESSENTIAL COMPONENTS OF REFLEXE ARCS
Receptor, Sensory neuron, Integration system, Motor neuron and Effector
a component of reflex arcs that reacts to stimuli
Receptor
a component of reflex arcs that conducts the afferent impulses to the CNS
Sensory neuron
a component of reflex arcs that consists of one or more synapses on the CNS
Integration system
a component of reflex arcs that conducts the efferent impulses from the integration center to an effector
Motor neuron
a component of reflex arcs that conducts muscle fibers or glands, respond to the efferent impulses by contracting or secreting a product, respectively.
Effector
What step (number) in reflex arcs where nerve impulse move along the axon of a sensory neuron toward the cell body located outside the cord
1
What step (number) in reflex arcs where from the cell body of the sensory neuron, the impulses are picked up by an interneuron lies within the cord
2
What step (number) in reflex arcs where The impulses are passed to the dendrites and the cell body of a motor neuron that lies ventrally within the cord.
