100

These are the three (3) types of muscles in the body

Smooth

Cardiac

Skeletal

100

These are the thin fibers that can either be thick (myosin) or thin (actin) and are responsible for muscle contraction

Myofilaments

100

This muscle of the neck is superficial and provides lateral flexion and rotation (tilting, turning, and bending the neck)

Sternocleidomastoid

100

This is the general location of the supinator, pronator teres, and pronator quadratus

Forearm [ulna and/or radius]

100

These cross two (2) or more joints and can be limited in ability to produce full muscular force when shortened across multiple joints

Multi-Joint Muscles

200

This skeletal muscle property refers to the ability of muscle to respond to a stimulus

Irritability

200

These are the two most common skeletal muscle fiber arrangements

Parallel

Pennate
200

This term applies to the coordinated, linked, predictable movement between scapula and humerus

Scapulohumeral Rhythm

200

This muscle is a triangular, superficial muscle that forms the rounded contour of the shoulder

Deltoid

200

This is the essential stability provided by active muscular contraction during movement

Dynamic stabilization

300

This muscle role acts in opposition to that of the mover/agonist

Antagonist

300

These are the three (3) types of attachments that connect muscle to bone

Direct

via Tendon

Aponeurosis


300

These three (3) muscles create scapular adduction

Trapezius
Rhomboids
Levator Scapulae

300

These three (3) muscles create elbow flexion

Biceps brachii
Brachialis
Brachioradialis

300

Name one (1) example of a force couple in the muscular system

Abdominals-Hamstrings

SIT (subscapularis, infraspinatus, teres minor)

Serratus Anterior-Trapezius

400

This type of muscle contraction displays no visible movement, meaning the muscle torque and resistance are equal

Isometric contraction
400

This is the nerve that carries impulses from the central nervous system (brain & spinal cord) to the effector organ (muscle)

Motor Neuron

400

These are the four (4) muscles that form a cuff about the head of the humerus

Supraspinatus

Infraspinatus

Teres minor

Subscapularis 

400

This is a wide, superficial back muscle that generates shoulder extension, shoulder adduction, and shoulder internal rotation

Latissimus dorsi

400

This occurs when a multi-joint muscle is unable to produce full range of motion (ROM) when actively contracting concentrically because it's shortened across two (2) or more joints simultaneously

Active Insufficiency

500

Which types of muscles are striated?

Skeletal

Cardiac

500

These are two (2) types of muscle fibers and their characteristics:

Slow-twitch fibers: are smaller in diameter, produce less tension, have a slower contraction time, and have a higher resistance to fatigue

Fast-twitch fibers: are larger in diameter, produce greater force, have a faster contraction time, and a lower resistance to fatigue

500

These are the five (5) scapular muscles

Trapezius (posterior)
Levator Scapulae (posterior)
Rhomboids (posterior)

Pectoralis minor (anterior)
Serratus anterior (anterior)

500

This muscle runs along the arm, is deep to the biceps brachii, and is recruited for almost all elbow flexion

Brachialis

500
