Sarcomere
Identify the four types of stimuli that can excite a neuron...
Mechanical, Thermal, Chemical, Electrical
This term represents a stored form of glucose which serves as a source of fuel or energy for the body.
Glycogen
Which of the following glial cells ensures the proper working order of peripheral nerves?
Satellite Cells
Movements such as radial and ulnar deviation occur in the _______ plane of motion.
Frontal Plane
This component of the sarcomere highlights the overlap of actin and myosin filaments.
A-Band
This component (i.e. lobe) of the brain is responsible for retaining sensory memory, also referred to as somatosensation.
This energy source within the muscle helps to ensure that an adequate supply of ATP is available within the muscle.
What happens to the myelin sheaths in the condition multiple sclerosis?
Multiple sclerosis is an autoimmune disorder. In this condition, the body attacks or begins to break down the myelin sheaths.
This condition is specific to the central nervous system and the spinal cord.
The ability for a muscle to recoil back to its original length is called....
The holding place for calcium within the muscle is ________. Once released, calcium attaches to _________ to initiate a muscle contraction.
Sarcoplasmic Reticulum; Troponin
The term ______ represents the group or collection of nerves exiting the spinal column.
Plexus
Of the three energy systems, list them from those that generate the most amount of energy to the least amount of energy.
Oxidative-Aerobic; Glycolytic-Lactic Acid; ATP-PCr
The term _____ represents a bundle of axons in the CNS, and the term ______ represents a bundle of axons in the PNS.
Dry Erase Board Challenge: Categorize the following exercises, and the plane of motion, it belongs to...
A: Biceps Curl (Elbow Flexion), B: Jumping Jacks (Hip Abduction/Adduction) C: Russian Twists (Trunk Rotation).
Biceps Curl: Sagittal, Jumping Jacks: Frontal; Russian Twists: Transverse Plane
This muscle fiber type contracts slowly, has a large amount of mitochondria and has the highest amount of fatigue resistance.
Type I Fibers; Slow Oxidative Muscle Fibers
This cranial nerve has both sensory and motor functions. It provides sensation to the face and movement of facial muscles.
Trigeminal (5)/(V)
In glycolysis, glucose is converted into pyruvate. What is it converted into without oxygen.
Lactic Acid
Differentiate between the terms proprioception and kinesthesia.
In the process of a muscle contraction, what is a power stroke?
Power stroke refers to the myosin heads attaching to actin's active sites, and pulling the actin filament towards the center of the sarcomere.
This muscle fiber type contracts quickly, has a low amount of mitochondria and has the highest fatigue rate of muscle fiber types.
Type IIb or Type IIx Muscle Fibers; Fast Glycolytic
Continuous conduction represents the continuation of a nerve impulse traveling along an unmyelinated neuron.
Comparatively, saltatory conduction represents the continuation of a nerve impulse traveling along a myelinated neuron. In comparison, this leads to a quicker transmission of the action potential.
Dry Erase Board Challenge: Draw an image that showcases how the ATP-PCr system works.
The energy provided allows the "free" phosphate to attach to ADP, to create a relatively constant supply of ATP.
What is Guillan Barr Syndrome?
Guillan Barr Syndrome is an auto-immune condition that involves the breakdown of myelin sheaths in the peripheral nervous system.
Describe what is meant by, "Wolff's Law"
Wolff's Law suggests that the body adapts to the type and amount of stress placed upon it.
