100
Elbow joints, knee joints, ankle joints and interphalangeal joints are examples of this articulation
What is a hinge joint
100
This pectoralis major is responsible for these movements
What is flexion, adduction, and medial rotation at the shoulder?
100
Muscle tissue, one of the four basic tissue groups, consists chiefly of cells that are highly specialized for one purpose. This purpose is
What is contraction?
100
Occurs in the same plane as flexion. Increases the angle at the joint
What is extension
100
The energy provided for a muscle contraction is provided by this
What is ATP?
200
The shoulder and hips are examples of this type of joint
What is a ball-and-socket joint?
200
The actions of this very large muscle group in the upper body helps with extension, adduction, abduction, and medial rotation at the shoulder
What is the latissimus dorsi?
200
These are formed by collagen fibers at the end of a skeletal muscle that attaches the muscle to bone.
What is a tendon?
200
This is defined as a movement away from the midline
What is ABduction?
200
This type of muscle helps a larger muscle work more efficiently
What is a synergist?
300
This joint that permits the greatest range of mobility of any joint in the body
What is the glenohumeral joint (shoulder joint)
300
Muscle(s) found in the upper arm and it's main actions are flexion at the elbow and shoulder along with supination.
What is the biceps brachii?
300
Individual muscle cells are surrounded by this type of connective tissue
What is endomysium?
300
This movement is characterized by a twisting motion of the foot that turns the foot outwards (laterally)
What is eversion?
300
This term is used to describe all the muscle fibers controlled by a motor neuron
What is a motor unit?
400
This *functional* category of joints permits the least amount of movement
What is synarthrosis
400
The rectus femoris is responsible for this movement
What is extension at the knee/flexion at the hip?
400
This region of the sarcomere that always contains only thin filaments is called the
What is the I band?
400
This movement is characterized by moving the thumb towards the surface of of the palm and the other fingers.
What is opposition?
400
This is responsible for the storage and release of calcium ions.
What is the sarcoplasmic reticulum?
500
This type of joint category permits more movement than synarthrosis. For example, distal joint between tibia and fibula
What is an amphiartrosis?
500
The semimembranous is found in the hamstring group and is responsible for these movements
What is flexion at the knee/extension and medial rotation at hip
500
At rest, the tropomyosin molecule is held in place by
What is actin?
500
This movement is defined as an extension past it's anatomical position
What is hyperextension?
500
This neurotransmitter is responsible for the first step in a muscular contraction
What is actylcholine (ACh)?
