What is the term for the biceps Brachii during forearm flexion?
Although a number of muscles may be involved in an action, the principal muscle involved is called the prime mover, or agonist. During forearm flexion, for example lifting a cup, a muscle called the biceps brachii is the prime mover.
What is the classification of skeletal muscle?
Skeletal muscles are voluntary muscles under the control of the somatic nervous system. The other types of muscle are cardiac muscle which is also striated and smooth muscle which is non-striated; both of these types of muscle tissue are classified as involuntary, or, under the control of the autonomic nervous system.
What is the term for the more movable muscle attachment?
A typical muscle has a central portion (the belly) and two or more attachment ends with tendons. The more stationary of the attachments is called the origin; the more movable attachment is called the insertion. SELECTED MUSCLES OF THE BODY.
What is the name of this muscle? – Related Questions
What are the 3 types of muscles?
The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.
What are the 5 types of muscle movements?
Now, lets look at the 5 types of muscle movements.
- Adductionis the moving of a body part toward the mid-line of the body.
- Abduction…is moving a body part away from the body.
- Flexion…
- Extension…
- Rotation… and last, rotation involves move a body part around an axis.
What is the muscle attachment joined to the less moveable part?
Origin – part of the muscle attached to the immovable or less movable bone. Insertion – part attached to the movable bone; insertion moves toward the origin.
Where the muscle attaches to the movable bone?
Overview. A tendon is a fibrous connective tissue that attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.
What is the most proximal attachment of a muscle?
Muscle origin refers to a muscle’s proximal attachment—the end of the muscle closest to the torso. For example, the bicep muscle’s origin is located at the shoulder.
What does distal attachment mean?
Muscle insertion refers to a muscle’s distal attachment—the end of the muscle furthest away from the torso. For example, the bicep insertion occurs at the elbow.
What are chest muscles called?
pectoralis muscle, any of the muscles that connect the front walls of the chest with the bones of the upper arm and shoulder. There are two such muscles on each side of the sternum (breastbone) in the human body: pectoralis major and pectoralis minor. Related Topics: muscle pectoralis major pectoralis minor torso.
What is fascia muscle?
What is fascia? Fascia is a thin casing of connective tissue that surrounds and holds every organ, blood vessel, bone, nerve fiber and muscle in place. The tissue does more than provide internal structure; fascia has nerves that make it almost as sensitive as skin. When stressed, it tightens up.
What is proximal position?
Proximal means nearer to the center (trunk of the body) or to the point of attachment to the body. If another reference point is given, such as the heart, the proximal point of another organ or extremity is the point closest to the heart, central rather than peripheral.
What are the 7 anatomical positions?
The main directions for parts of the body are superior, inferior, anterior, posterior, medial, and lateral, whereas the terms proximal and distal are more appropriate for the limbs (Figs. 1.6.
What are the 4 body planes?
Anatomical Planes
- Coronal Plane or Frontal Plane.
- Sagittal Plane or Lateral Plane.
- Axial Plane or Transverse Plane.
What is an example of distal?
Distal refers to sites located away from a specific area, most often the center of the body. In medicine, it refers to parts of the body further away from the center. For example, the hand is distal to the shoulder. The thumb is distal to the wrist.
What is an example of proximal?
In medicine, refers to a part of the body that is closer to the center of the body than another part. For example, the knee is proximal to the toes. The opposite is distal.
What is an example of medial in anatomy?
Medial means toward the middle or center. It is the opposite of lateral. The term is used to describe general positions of body parts. For example, the chest is medial to the arm.
What is an example of proximal and distal?
Proximal – toward or nearest the trunk or the point of origin of a part (example, the proximal end of the femur joins with the pelvic bone). Distal – away from or farthest from the trunk or the point or origin of a part (example, the hand is located at the distal end of the forearm).
Is the knee proximal or distal to the hip?
Because the hip lies closer to the axial skeleton than the knee does, we can say that the hip is proximal to the knee.
