Week 3 Lab Flashcards
Dynamometer
, is a device that measures force, torque or power.
Emg
diagnostic procedure to assess the health of muscles and the nerve cells that control them
Electromyography (EMG)
measures muscle response or electrical activity in response to a nerve’s stimulation of the muscle.
Motor unit
-Nerve muscle function increases force of muscle contraction
is made up of a motor neuron and all of the skeletal muscle fibers innervated by the neuron’s axon terminals, including the neuromuscular junctions between the neuron and the fibres. Groups of motor units often work together as a motor pool to coordinate the contractions of a single muscle.
Muscle fatigue
-Lactic acid goes into muscle and atp decreases NaK+ imbalance (exhaustion )
decrease in maximal force or power production in response to contractile activity.
Strop test
The Stroop test can be used to measure a person’s selective attention capacity and skills,
Left hemisphere
The left hemisphere controls the right-hand side of the body and receives information from the right visual field, controlling speech, language, and recognition of words, letters, and numbers
Right hemisphere
he right hemisphere controls creativity, spatial ability, artistic, and musical skills.
Left hemisphere
In general, the left hemisphere controls speech, comprehension, arithmetic, and writing
Right hemisphere
controls creativity, spatial ability, artistic, and musical skills.
Short term memory
Short-term memory is the capacity for holding a small amount of information in an active, readily available state for a short interval. For example, short-term memory holds a phone number that has just been recited. T
What happpens to the for r as you countinie to clean muscles in muscle fatigue experiment
Muscle fatigue
functional unit of skeletal muscle, essential for proper contraction.
The sarcomere
What are Skelton muscle innervated by?
Single motor axon
