What is the antagonistic muscle for the latissimus dorsi?
Table of Contents
The latissimus dorsi: agonistic: teres minor, posterior deltoid, infraspinatus, rhomboid major, upper trapezius, pectoralis major, pectoralis minor, serratus anterior, teres major. antagonistic: anterior deltoid, middle deltoid, levator scapulae, rhomboid minor, supraspinatus, lower trapezius, middle trapezius.
What muscle works synergistically with the latissimus dorsi?
Both muscles have the task of adducing, extending and rotating the humerus. Synergistic to the latissimus dorsi is the pectoralis major, for two functions out of three (adduction and intrarotation of the humerus) and the long head of the triceps (extension of the humerus).
What is the action of the latissimus dorsi muscle?
Latissimus dorsi works collaboratively with the teres major and pectoralis major to perform actions of the upper extremity. Together, these muscles will work to adduct, medially rotate and extend the arm at the glenohumeral joint.
Which are antagonistic muscles?
In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist….Antagonistic muscle pairs.
| Biceps | Triceps |
|---|---|
| Pectoralis major | Latissimus dorsi |
What is the Infraspinatus antagonist?
Antagonist: Subscapularis, pectoralis major, and latissimus dorsi.
What muscle works synergistically with deltoid?
The combination of deltoid muscle and teres minor contributes significantly to external rotation in 90° of abduction.
Which muscles do pull-ups work?
Pullups use your lats and biceps primarily, while also recruiting your deltoids, rhomboids, and core. These are the muscles you’ll need to strengthen. We’ve curated five exercises as a starting point to train for pullups.
Which of the following is not an action of the latissimus dorsi?
Lateral (external) rotation of the arm at the shoulder is NOT an action created by the latissimus dorsi as this action is caused by the teres minor muscle.
Why is it called latissimus dorsi?
Definition. The latissimus dorsi muscle, named after the Latin term latus (wide) and dorsi (back), is a flat, wing-like muscle that stretches from its origins at the lower thoracic vertebrae, lower ribs, scapula and iliac crest and attaches or inserts at a groove in the bone of the upper arm (humerus).
How do you fix a tight latissimus dorsi?
1. Active floor stretch
- From a kneeling position, sink your hips back and place your right forearm along the floor.
- Lean your weight onto your right arm and stretch out your left arm, reaching out through your fingertips.
- Hold this position for a few seconds.
- Return to the starting position.
- Repeat 10 times.
Why does my latissimus dorsi muscle hurt?
What causes latissimus dorsi pain? The latissimus dorsi muscle is used the most during exercises that involve pulling and throwing. Pain is usually caused by overuse, using poor technique, or not warming up before exercising.
What is the antagonist of the latissimus dorsi?
Latissimus Dorsi: Antagonist. An antagonist is a muscle that opposes the action of another muscle. Therefore, antagonists of the latissimus dorsi would be any muscle that opposes the actions of adduction, medial rotation, and extension of the humerus.
What are the opposing movements of the latissimus dorsi?
The opposing movements of the latissimus dorsi include abduction, external rotation, and flexion of the humerus or upper arm. The muscles that perform these movements, and therefore are antagonists of the latissimus dorsi, include the deltoid, supraspinatus, biceps brachii, coracobrachialis, pectoralis major, infraspinatus, and teres minor.
Where does latissimus dorsi attach to the upper arm?
Latissimus Dorsi: Insertion. The latissimus dorsi inserts or attaches to the humerus, the long bone of the upper arm. Specifically, this muscle inserts on the intertubercular groove of the humerus, also known as the ‘bicipital groove’.
What are the Lat muscles?
The muscles that are being described in these athletes are called the latissimus dorsi muscles, or lat muscles for short. The latissimus dorsi is a thin, wide, triangular-shaped muscle located at each side of the back, right under each arm. The latissimus dorsi muscle (shown in red).
