What is aponeurosis and its function?
An aponeurosis is a type of connective tissue found throughout the body. Aponeuroses provide an attachment point for muscles to connect to bone, and can also envelope muscles and organs, bind muscles together, and bind muscles to other tissues. They are important for muscle movement and posture.
What is ligament aponeurosis?
Aponeuroses, fasciae, ligaments and tendons are structures seen along with muscles. Fasciae are the auxillary tissues that connect muscle to muscle while ligaments are connective tissues that connect one bone to another bone. Aponeuroses and tendons are connective tissues that connect muscles to bones.
What is the linea alba in a cat?
The linea alba is a dense collagenous band found on the ventral midline of the abdominal wall extending from the base of the xiphoid process to the prepubic tendon (ie, cranial pubic ligament). Cats have a relatively wider, more transparent linea alba that is easier to visually identify as compared with dogs.
What is the deepest muscle of the cat and human abdominal wall?
Transversus Abdominis This is thinnest and deepest of the 3 anterolateral abdominal wall muscles. It originates from the lower 6 costal cartilages, lumbar vertebrae, iliac crests, and iliopsoas fascia.
Is aponeurosis a fascia?
An aponeurosis (/ˌæpənjʊəˈroʊsɪs/; plural: aponeuroses) is a type or a variant of the deep fascia, in the form of a sheet of pearly-white fibrous tissue that attaches sheet-like muscles needing a wide area of attachment.
Is aponeurosis a flat tendon?
aponeurosis, a flat sheet or ribbon of tendonlike material that anchors a muscle or connects it with the part that the muscle moves. The aponeurosis is composed of dense fibrous connective tissue containing fibroblasts (collagen-secreting spindle-shaped cells) and bundles of collagenous fibres in ordered arrays.
What are your abs called?
rectus abdominis muscle
The human rectus abdominis muscle. costal cartilages of ribs 5-7 Xiphoid process of sternum. The rectus abdominis muscle, also known as the “abdominal muscle” or simply the “abs”, is a paired muscle running vertically on each side of the anterior wall of the human abdomen, as well as that of some other mammals.
What muscle is not found in humans but in cats?
Clavotrapezius, acromiotrapezius, & spinotrapezius are back muscles in the cat. There is one trapezius muscle in the human. The levator scapulae ventralis is found in the cat but is missing in the human.
What does aponeurosis mean?
Aponeuroses (plural of aponeurosis: απο, “away” or “of”, and νευρον, “sinew”, and pronounced ap·o·neu·ro·sis) are layers of flat broad tendons. They have a shiny, whitish-silvery color, are histologically similar to tendons, and are very sparingly supplied with blood vessels and nerves.
How does the aponeurosis of the pennate muscle work?
Pennate muscles, in which the muscle fibers are oriented at an angle to the line of action, typically have two aponeuroses. Muscle fibers connect one to the other, and each aponeurosis thins into a tendon which attaches to bone at the origin or insertion site.
What is the primary function of the aponeurose?
Their primary function is to join muscles and the body parts they act upon, whether it be bone or other muscles. They have a shiny, whitish-silvery color, are histologically similar to tendons, and are very sparingly supplied with blood vessels and nerves. When dissected, aponeuroses are papery and peel off by sections.
What kind of tissue is an aponeurosis made of?
Anatomical terminology. An aponeurosis ( / ˌæpənjʊəˈroʊsɪs /; plural: aponeuroses) is a type or a variant of the deep fascia, in the form of a sheet of pearly-white fibrous tissue that attaches sheet-like muscles needing a wide area of attachment.
