Insertions / attachments/ origins kinesology Flashcards
Origin of muscle
Where the end of a muscle is anchored to a bone and does not move. Located more proximal
Insertion of muscle
The more mobile attachment of the muscle that connects it to the bone. Located more distal
Prime Mover
the primary muscle responsible for a specific movement
Agonist
Another name for prime mover
Antagonist
The muscle that performs the opposite movement of the agonist
Synergists
Muscles that share the same action the agonist
Fixator
Muscles that act to stabilize a body part so that another muscle can act on an adjacent body part.

Hamate
A synovial hinge joint formed between the radial head and the capitulum of the humerus that allows flexion and extension. This joint sits side by side with the humeroulnar joint.
Humeroradial joint
A synovial hinge joint formed between the trochlear notch of the ulna and the trochlea of the humerus that allows flexion and extension. This joint sits side by side with the humeroradial joint.
Humeroulnar joint
Synovial gliding joints formed between individual carpal bones of the wrist.
Intercarpal joints
Connective tissue membrane between the radius and ulna.
interosseous membrane in the forearm
A synovial hinge joint formed between the phalanges
each finger has two, the thumb only has 1
A synovial hinge joint formed between the phalanges
Bony prominence of the humerus located lateral to the olecranon process that serves as an attachment site for tendons of the wrist and hand extensors.
Lateral epicondyle of the humerus
Carpal bone on the dorsal surface of the wrist
between the scaphoid and triquetrum
Lunate
Rounded eminence on the medial distal portion of the humerus that articulates with the ulna.
Medial Condyle of the humerus / trochlea
A bony prominence on the distal medial humerus.
Medial epicondyle of the humerus
How many metacarpals are there
5
A synovial ellipsoid joint formed between the metacarpals and the proximal phalanges
Metacarpophalangeal joint
the olecranon process is the attached site for which muscle
The triceps
attachment site for the palmaris longus tendon
Palmar aponeurosis
Muscle of the forearm that tenses the palmar fascia and flexes the wrist and elbow; it crosses the wrist, but not the hand and finger joints.
Palmar longus
Carpal bone on the ulnar aspect of the wrist that serves as the insertion point for the flexor carpi ulnaris.
Piriformis
Depression on the lateral side of the coronoid process of the ulna that articulates with the radius.
Radial notch
A prominence on the anterior proximal radius that serves as the distal attachment site for the biceps brachii.
Radial tuberosity
A synovial ellipsoid joint formed between the distal end of the radius and the proximal row of carpal bones
radiocarpal joint
This joint resides in the upper part of the neck between the first and second cervical vertebrae, also known as the atlas and axis.
The atlanto-axial joint
classified as a condyloid/ellipsoid synovial joint. It is formed by the articulations of the superior facets of the atlas (C1) and the occipital condyles,
Atlanto-occipital joint
One of five synovial joints formed by the articulations of the distal row of carpal bones and the metacarpal bones.
Carpometacarpal joint
coxofemoral joint aka
hip joint
A synovial hinge joint formed between the proximal, medial, and distal phalanges that allows flexion and extension of the toes.
Interphalangeal joint
A synovial gliding joint formed between the cuneiforms, navicular, and cuboid bones that contributes to foot stability and mobility.
Intertarsal joint
joint that are located between adjacent vertebrae in the spine.
Intervertebral disc joint
A synovial gliding joint formed between the lateral end of the clavicle and the medial edge of the acromion process of the scapula.
acromioclavicular joint
A synovial gliding joint formed between the lateral end of the clavicle and the medial edge of the acromion process of the scapula.
acrimoclaivaular joint
A synovial ellipsoid joint formed between the metacarpals and the proximal phalanges
Metacarpophalangeal joint
A synovial ellipsoid joint formed between the metacarpals and the proximal phalange
Metatarsophalangeal joint
A synovial joint formed between the posterior surface of the patella and the intercondylar groove of the femur
patellofemoral joint
Tibiofemoral joint also known as the
Knee
____ are generally called spinal joints when in combination with intervertebral disc joints

adduct
Which head of the hamstrings does not originate at the ischium, but rather from the posterior femur?
short head of the bicep femoris
The main flexor of the lumbar spine is the:
Rectus abdominus
