What movement is the pectoralis major responsible for?
The pectoralis major extends across the upper part of the chest and is attached to a ridge at the rear of the humerus (the bone of the upper arm). Its major actions are adduction, or depression, of the arm (in opposition to the action of the deltoideus muscle) and rotation of the arm forward about the axis of the body.
What does pectoralis major pain feel like?
The first sensation felt when the pectoralis major muscle is torn is sudden pain. This pain is usually felt at the front of the armpit and is sometimes felt across the chest. At the same time you may also feel something 'tearing' in your chest. In minor tears you may be able to continue participating with slight pain.
What movement does the deltoid perform?
Deltoid muscle functions include: Arm abduction, which means raising your arm out to the side of your body. Compensation for lost arm strength if you have an injury, such as a rotator cuff tear. Flexion (moving your arm forward, toward an overhead position) and extension (moving your arm backward, behind your body).
What is the action of the triceps?
The triceps brachii is a large, thick muscle on the dorsal part of the upper arm. It often appears in the shape of a horseshoe on the posterior aspect of the arm. The primary function of the triceps is the extension of the elbow joint.
How do you relieve pectoralis major pain?
TreatmentRest. Stop activity as soon as you notice pain. ... Ice. Apply ice or a cold pack to the affected area for 20 minutes up to three times a day.Compression. Consider wrapping any areas of inflammation with an elastic bandage but don't wrap too tightly as it may impair circulation.Elevation.
How long does it take for a pectoral muscle to heal?
How long should recovery take for torn pec muscle? Generally, low-grade tears take 4-6 weeks to recover, while high-grade tears can take 3-4 months. Remember, recovery time is not only determined by the grade of injury but how quickly you heal after surgery. Therefore, healing times may differ from case to case.
Are deltoids push or pull?
This is why front delts are considered pushing muscles (as in shoulder press) and side delts are considered pulling muscles (as in upright rows).

What are the 3 deltoid muscles?
The deltoid consists of three parts, also known as heads: The anterior deltoid is located at the front of the shoulder. The posterior deltoid is located at the back of the shoulder. The lateral deltoid is sandwiched between the anterior and posterior deltoids.
Are triceps push or pull?
Pushing: chest, shoulders, and triceps. Pulling: back, biceps, and forearms.
Why is it called a tricep?
Etymology. It is sometimes called a three-headed muscle (Latin literally three-headed, tri - three, and ceps, from caput - head), because there are three bundles of muscles, each of different origins, joining at the elbow.
What are the 3 muscles of the triceps?
The triceps brachii runs the length of the upper arm from the scapula in your shoulder down to the elbow joint. Although it is one muscle, there are three distinct heads of the triceps: the long head, medial head, and lateral head.

What does a strained pec minor feel like?
Symptoms of the pec minor injury include; Pain in between shoulder blades in upper back. Pain and/or numbness through the inner arm, inside of elbow, into wrist, hand and 4th and 5th fingers. A sore/tight pec minor can contribute to a rounded shoulder posture as the muscle pulls the shoulder forward.
Did I strain or tear my pec?
Signs and symptoms of a pec strain Most people will report a specific moment in time where they feel a “tearing “or “popping“ sensation in the chest or around the armpit. Immediately they will feel pain in the chest and a loss of strength if they have a grade 2 or 3 tear.
Horizontal Range Formula: Projectile Motion Formula, Examples
A projectile is an object that we give an initial velocity, and gravity acts on it. Projectile’s horizontal range is the distance along the horizontal plane. Moreover, it would travel before it reaches the same vertical position as it started from. Learn horizontal range formula here.
Projectile Motion: Time of flight, time of ascent and descent, range
Time of Ascent: The time taken by the body to reach the maximum height is called the time of ascent. Let v 0 = Velocity of projection and θ = Angle of projection. Resolving v 0 into two components viz. v 0 Cosθ the horizontal component. And v 0 Sinθ the vertical component. Consider vertical Component v 0 Sinθ. Due to this component, there is the vertical motion of the body.
What is the motion of the ball called in basketball?
The motion of the ball is in the form of a projectile. Hence, it is referred to as projectile motion .
What is the motion of a particle thrown obliquely near the Earth's surface called?
The path of such a particle is called a projectile and the motion is called projectile motion.
What is Projectile Motion?
When a particle is thrown obliquely near the earth’s surface, it moves along a curved path under constant acceleration that is directed towards the centre of the earth (we assume that the particle remains close to the surface of the earth). The path of such a particle is called a projectile and the motion is called projectile motion.
What determines the dimension of a body's motion?
Thus, it can be concluded that the minimum number of coordinates required to completely define the motion of a body determines the dimension of its motion.
What is the primary force acting on a projectile?
A projectile is any object thrown into space upon which the only acting force is gravity. The primary force acting on a projectile is gravity. This doesn’t necessarily mean that other forces do not act on it, just that their effect is minimal compared to gravity.
Is a body thrown near the surface a two dimensional motion?
This implies that as long as a body is thrown near the surface, the motion of the body can be considered as a two-dimensional motion, with acceleration only in one direction.
