How did we Assess Coordination in the Lab?
|
1) touching the tip of the nose with eyes open and closed
2) Make fingers come together with eyes open and close |
|
|
How did we Assess Balance in the Lab
|
1) walking on a line with eyes closed and open
2) Stood in the same spot with eyes open and closed to see how much we swayed |
|
|
How did we Assess Movement and Balance in the Lab
|
Moving our foot onto our shins and sliding them down
|

|
What is a Spinal reflexes and reflex arcs?
|
A reflex action is a rapid automatic response to a single stimulus; spinal reflexes are those primarily controlled by the spinal cord
|
|
|
The structural basis of a reflex action (the neural pathway) is called a _____ _____ and it mostly consists of sensory, motor, and inter neurons
|
Reflex arc
|
|
|
How did we Assess Bicep Reflex and Tricep Reflex?
|
We striked the Tendon with the pointed and of the reflex hammer and observe the response
|
|
|
Patellar or Knee-jerk reflex
|
When you tap a tendon of the upper thigh muscle just below the knee-cap, the quadriceps is made to stretch, stimulating the receptors in the muscle, which now send impulses to the spinal cord. The motor nerve fibers from the spinal cord will then cause the contraction of the quadriceps to prevent further stretching; this is seen as a jerking movement of the lower leg
|
|
|
Reaction time of kneejerk reflex and learned reflexes: The neural pthway in a knee-jerk reflex is direct, and involves only 2 types of neurons: _____ and _____
|
sensory and motor neurons ( hence called a monosynaptic reflex)
|
|
|
When impulses reach the spinal cord, they are immediately channeled into the _____ neuron via the synapse, and the motor nerve fiber then stimulate quadriceps to contract, causing the knee-jerk
|
Motor
|
|
|
In _____ _____, many neurons of the sensory, motor and inter neurons are involved, and the neural pathway of such reflex actions is very long and complex
|
Learned Reflexes
