Proximal muscles are commonly affected in myopathies due to their reliance on specific muscle fibers that are often more susceptible to metabolic and inflammatory processes. These muscles, which include those in the shoulders, hips, and thighs, are typically involved in core stability and limb movement, making them more vulnerable to dysfunction. Additionally, many myopathies target the muscle's structural components, such as the sarcomeres or membranes, which can particularly impact proximal muscle strength and function. As a result, weakness in these areas is often one of the first clinical signs of myopathy.

What are some congenital conditions classed as congenital myopathies?
Congenital myopathies are a group of myopathies, usually present from birth, that display structural changes in the skeletal muscles. The list of diseases defined as congenital myopathies varies.
What is the most common disease in muscles?
They are muscular dystrophies, myopathies, multiple sclerosis.
Why are proximal muscles usaully larger and stronger than distal muscles?
because they are larger
What tissues are usually affected by mitochondrial myopathies?
Mitochondrial myopathies typically affect tissues with high energy demands, such as skeletal muscles, heart muscles, and the central nervous system. Symptoms may include muscle weakness, exercise intolerance, and neurological problems due to impaired energy production.
What role do proximal muscles play in maintaining posture and stability in the human body?
Proximal muscles, located closer to the core of the body, are essential for maintaining posture and stability. These muscles provide support and control for movements, helping to keep the body balanced and upright. Strong proximal muscles are crucial for overall stability and proper alignment of the body.
Is the skin of the lower arm proximal to the muscles below it?
The skin is superficial to the muscles. The muscles are deep to the skin.
What are the functions and movements controlled by the proximal limb muscles?
The proximal limb muscles control functions and movements such as lifting, pushing, pulling, and stabilizing the body. These muscles are responsible for movements involving the shoulder, upper arm, and hip joints.
What is a disease that attacks the muscular system?
In general diseases that attack the muscles are called myopathies. Muscular dystrophy would be one example.
What muscles abduct the proximal phalanges?
The abductor digiti minimi muscle abducts the fifth proximal phalanx. The abductor pollicis brevis abducts the thumb. The dorsal interossei muscles abduct the other fingers.
What are the symptoms of inclusion body myostis?
Weakness and impairment of muscle function are the hallmarks of IBM, and weakness distribution is variable, with both proximal (closest to the center of the body) and distal (farthest from the center of the body) muscles affected.
What is the anatomy of the proximal hamstring muscles and how do they contribute to hip and knee function?
The proximal hamstring muscles are located at the back of the thigh near the hip. They consist of three main muscles: the semitendinosus, semimembranosus, and biceps femoris. These muscles play a crucial role in hip extension and knee flexion. They help in activities like running, jumping, and bending the knee. Injuries to these muscles can affect the ability to perform these movements effectively.
What is the proximal epiphyseal line on the humerus called?
The proximal epiphyseal line on the humerus is commonly referred to as the "greater tubercle." It is a prominent bony projection located near the head of the humerus and serves as an attachment point for several muscles of the shoulder, including the rotator cuff. This line represents the site of growth plate fusion that occurs after skeletal maturity.
