What does the scapula protect in the body?
Scapula is the scientific term for shoulder blade. It provides a foundation for the attachments of the muscles that move the arm.There are many functions of the scapula. It forms part of the shoulder girdle and many (16) muscles are associated with it.The actions that the muscles have on it include: elevation (shrugging), depression (slumping), abduction, adduction, rotation, and tipping.The scapula omo (shoulder blade) is the bone which connects the humerous (arm bone) to the clavicle (collar bone) Movements of the scapula are brought about by scapular muscles: Elevation, Depression, Protraction, Retraction, Lateral rotation, Medial rotation, Upward Rotation, Downward Rotation, Anterior Tipping, and Posterior Tipping
What muscle originates on the distal anterior humerus and inserts onto the coronoid process of the ulna to cause arm reflexion?
The brachialis muscle originates on the distal anterior humerus and insert at the coronoid process. The function of the brachialis is flexion at the elbow.
What does swelling under the scapula mean?
Swelling under the scapula could be a sign of various conditions such as muscle strain, inflammation, or even an underlying injury. It is important to get it checked by a healthcare provider to determine the exact cause and appropriate treatment.
Does the trapezius contract?
Trapezius muscle- located from the skull through the cervical and thoracic vertebrae to the lateral 1/3 of the clavicle and spine of scapula. Function: Elevates, Depresses, Retracts, and rotates the scapula up and down. Innervated by the Spinal Accessory Nerve
The primary muscles involved in torticollis are?
The primary muscles involved in torticollis are the sternocleidomastoid muscle and the trapezius muscle. These muscles are responsible for controlling the position and movement of the head and neck. Injury or spasm of these muscles can cause the characteristic head tilt and rotation seen in torticollis.
How does the stretch reflex cause the quadriceps femoris muscle group to contract?
Tapping on the patellar tendon stretches receptors called the muscle spindles in the quadriceps muscle group of the anterior thigh. This stimulus evokes a rapid motor reflex to contract the quadriceps and shorten the muscles. This process is called the patellar reflex.
What is a anterior osteophyte formation in cervical spine Can it cause spasms and dizziness and tremors in the neck?
An anterior osteophyte formation in the cervical spine refers to a bony outgrowth in the front portion of the vertebrae. It can potentially cause muscle spasms by irritating surrounding structures and nerve roots. However, dizziness and tremors in the neck are less commonly associated with osteophyte formation, and evaluation by a healthcare provider is recommended to determine the exact cause of these symptoms.
Scapula pain is cause by what?
Scapula pain can be confused with many other things. First you should have a thorough examination to make sure that the pain you think is in your scapula isn't actually something else. Basically if the pain is actually the scapula there are 2 possibilities: 1. Snapping Scapula Syndrome which can sometimes be helped with some treatment and physical therapy. Though, from personal experience a very similar pain seems to be on the rise among young men who lift weights. In that case, a reduction in specifically the "bench press" or other pectoralis workouts seems to help; especially when a focus on opposing back muscles is encouraged. A stronger back is frequently helpful. 2. A pinched nerve which could be from the location itself being caused by a structural deformity in the scapula or more proximally from a pinched nerve root in the neck. Hope this helps, Omar
Where does fluid blockage in eye cause glaucoma?
Anterior segment (contains aqueous humor)
Can low potassium cause muscle pain?
Yes, low potassium may cause muscle pain.
Can high stress cause an anterior infarction?
Yes, high stress can contribute to the development of an anterior infarction (heart attack). Stress can lead to an increase in blood pressure and heart rate, which in turn can strain the heart muscle and potentially trigger a heart attack, particularly in individuals with preexisting heart conditions. It is important to manage stress levels for overall heart health.
Does Muscle glycogen cause muscle contraction?
no, lactic acid does
