What is a ring of skeletal muscle that regulates the movement of a bolus into the esophagus?
The ring of skeletal muscle that regulates the movement of a bolus into the esophagus is called the upper esophageal sphincter (UES). The UES opens to allow the passage of food and liquid into the esophagus during swallowing and then closes to prevent aspiration into the trachea.
What type of muscle is capable of rapid contraction and causes skeletal movement?
Skeletal or voluntary muscle is capable of rapid contraction and is responsible for skeletal movement.
What cell regulates movement?
Muscle cells, also known as myocytes, primarily regulate movement in the body. There are three types of muscle cells: skeletal, cardiac, and smooth. Skeletal muscle cells enable voluntary movement of the skeleton, cardiac muscle cells control the heart's rhythmic contractions, and smooth muscle cells manage involuntary movements in various organs. Additionally, neurons play a critical role in coordinating and signaling these movements.
Which type of muscle has a direct effect on your bones?
Skeletal muscle has a direct effect on bones. When skeletal muscles contract, they pull on the bones to create movement at the joints. This movement is essential for activities such as walking, running, and lifting.
The structure storing calcium in the skeletal muscle fibers at rest is the?
The structure responsible for storing calcium in skeletal muscle fibers at rest is the sarcoplasmic reticulum. This organelle regulates the release of calcium ions during muscle contraction to trigger the muscle fiber to contract.
What type of movement does the autonomic system control?
The somatic nervous system regulates skeletal muscle tissue, while the ANS services smooth muscle, cardiac muscle, and glandular tissue.

What type of muscle is capable of rapid contraction and causes skeletal movement?
Skeletal or voluntary muscle is capable of rapid contraction and is responsible for skeletal movement.
Which part of the brain regulates muscle tone and coordination?
Cerebellum
What is the region of brain concerned with coordination and skeletal muscle called?
Cerebellum
What Is a characteristic of a skeletal muscle cell?
A key characteristic of a skeletal muscle cell is its striated appearance, which results from the organized arrangement of actin and myosin filaments within the muscle fibers. These cells are multinucleated, meaning they contain multiple nuclei per cell, which aids in muscle growth and repair. Additionally, skeletal muscle cells are under voluntary control, allowing for conscious movement and coordination.
What term means the lack of the muscle coordination during voluntary movement?
Ataxia: the lack of muscle coordination during voluntary movement.
What muscle makes our arms legs and head move?
The primary muscle responsible for moving our arms and legs is the skeletal muscle, which is under voluntary control and enables movement by contracting and relaxing. In the head, muscles like the sternocleidomastoid and facial muscles facilitate movement and expression. All these muscles work in coordination with the skeletal system and the nervous system to produce movement throughout the body.
How does the contraction of the I band contribute to the overall function of skeletal muscle?
The contraction of the I band in skeletal muscle helps to shorten the muscle fibers, allowing for movement and muscle contraction. This contributes to the overall function of skeletal muscle by enabling the muscle to generate force and produce movement.
What type of tissue is the skeletal muscle?
Skeletal muscle is a striated muscle used to control movement of specific body parts
What do skeletal muscle produce?
movement or heat
Which muscle type is voluntary in action?
The skeletal muscle is the only type of muscle which is voluntary.
