Lecture on Brain Function and Muscle Physiology

This set of flashcards covers key vocabulary and concepts related to brain function, muscle physiology, and relevant psychological tests as discussed in the lecture.

Cerebral Lateralization

The specialization of the brain's hemispheres to perform different tasks.

Stroop Test

A psychological test of our reaction time that demonstrates the interference between reading words and recognizing colors.

Selective Attention Test

An assessment of an individual's ability to focus on specific stimuli while ignoring others.

Short-Term Memory

The capacity to store a limited amount of information for a short period, typically around 7-12 'chunks' of data.

EMG (Electromyography)

A technique used to record the electrical activity of muscles.

Motor Unit

A motor neuron and the muscle fibers it innervates, essential for muscle contraction.

Muscle Fatigue

The decline in ability of a muscle to generate force.

Neuromuscular Junction

The synapse between a motor neuron and a muscle fiber where neurotransmitters transmit signals for contraction.

Dominant Arm

The arm that is typically stronger or more coordinated, often used for measurements in muscle strength tests.

Dynamometer

An instrument used for measuring force or power, often utilized in hand grip strength tests.
