What spasmodic is a stiff neck due to contraction of the neck muscles that pull the head toward the affected side?
Also known as a wry neck, spasmodic torticollis is a stiff neck due to spasmodic contraction of the neck muscle. The spasm causes the head to be pulled toward the affected side.

What is A stiff neck due to a spasmodic contraction of the neck muscles?
Also known as a wry neck, spasmodic torticollis is a stiff neck due to spasmodic contraction of the neck muscle. The spasm causes the head to be pulled toward the affected side.
The first step toward generating a skeletal muscle contraction is The first step toward generating a skeletal muscle contraction is?
stimulation of the muscle by a nerve ending.
During muscle contraction the moves toward the?
During muscle contraction, the Z-lines move closer together as the sarcomeres shorten. This is due to the sliding of actin and myosin filaments past each other, resulting in the contraction of the muscle.
What are the muscles called that bring a body part toward the body?
The muscles that bring a body part toward the body are called adductor muscles. They are responsible for moving a part of the body closer to the midline.
Five golden rules of gross skeletal muscle activity?
1. All muscles cross at least one joint. 2. Typically, the bulk of muscle lies proximal to the joint crossed. 3. During contraction, the muscle insertion moves toward the origin. 4. All muscles have at least two attachments (origin and insertion). 5. Muscles always pull, they never push.

stimulation of the muscle by a nerve ending.
What is the protein filament that slides inward toward the middle of a sarcomere during a muscle contraction?
Actin
What causes lymph to move toward the heart?
The lymph is circulated via muscle movement. The lymphatic system is not closed and has no central pump; thus transport is slow and sporadic. Lymph movement occurs due to peristalsis (propulsion of the lymph due to alternate contraction and relaxation of smooth muscle), valves, and compression during contraction of adjacent skeletal muscle and arterial pulsation.
What are the 3 layers of powerful muscles of the stomachs wall?
The stomach wall consists of three layers of powerful muscles known as the muscularis externa. These layers include the outer longitudinal layer, the middle circular layer, and the inner oblique layer. Together, these muscles facilitate the churning and mixing of food, as well as the movement of gastric contents toward the small intestine. This coordinated contraction aids in digestion and the breakdown of food.
What are the muscles called that brings a body part toward the body?
Adductors
Where is blood flow due to skeletal contraction found?
Blood flow due to skeletal contraction is primarily found in the muscles of the limbs, particularly during physical activity. When skeletal muscles contract, they compress nearby blood vessels, which helps to propel blood back toward the heart through the venous system. This process, known as the "muscle pump," enhances circulation and improves oxygen delivery to tissues during exercise. Additionally, it plays a crucial role in maintaining venous return, especially in the legs.
Which Muscle movement in myosin heads of the thick filaments pull on the thin filaments causing the thin filaments to slide toward the center of the sarcomere?
Flexing of the cross bridge (power stroke)
