Suspensory Ligaments of the Ciliary Body Suspensory Ligaments of the Ciliary Body: The suspensory ligaments of the ciliary body are ligaments that attach the ciliary body to the lens of the eye. Suspensory ligaments enable the ciliary body to change the shape of the lens as needed to focus light reflected from objects at different distances from the eye.

Gross Anatomy The posterior cricoarytenoid muscles function to rotate the arytenoid cartilages laterally, thereby abducting the vocal cords. Their action opposes that of the lateral cricoarytenoid muscles. The lateral cricoarytenoid muscles function to rotate the arytenoid cartilages medially, thereby adducting the vocal cords. The main function of the transverse arytenoid muscle is adduction of the vocal cords.

ligament A ligament is the tissue that connects two bones to form a joint. It's tough and fibrous, which means that when it tears, a ligament can take quite a while to heal and might even require surgery. Ligament comes from the Latin ligare meaning to bind, tie, which is precisely what a ligament does. Ligaments only connect bones to bones. Ligaments allow for range of motion. Think of how your knee or elbow is able to move up and down like a hinge. That's thanks to the ligaments connecting the bones to form knee and elbow joints.

Horse Tendons and Ligaments There are four main tendons and ligaments at the back of the horse's leg that do the majority of the work: suspensory ligament, inferior check ligament, deep digital flexor tendon and the superficial digital flexor tendon. In a horse's forelegs, these four structures are the most commonly injured tendons and ligaments.

Papillary muscle There are five total papillary muscles in the heart; three in the right ventricle and two in the left. The anterior, posterior, and septal papillary muscles of the right ventricle each attach via chordae tendineae to the tricuspid valve. The anterior and posterior papillary muscles of the left ventricle attach via chordae tendineae to the mitral valve. Blood supply. The mitral valve papillary muscles in the left ventricle are called the anterolateral and posteromedial muscles. 1  Anterolateral muscle blood supply: left anterior descending artery - diagonal branch (LAD) and left circumflex artery - obtuse marginal branch (LCX)

Serous demilune A serous demilune or Crescents of Gianuzzi is a cap in the shape of a half-moon (hence the name demilune) on some salivary glands.Serous demilunes are the serous cells at the distal end of mucous tubuloalveolar secretory unit of certain salivary glands.These demilune cells secrete the proteins that contain the enzyme lysozyme, which degrades the cell walls of bacteria. In this way, lysozyme confers antimicrobial activity to mucus.he serous demilune is an artifact from traditional methods of preparing samples. Samples are traditionally preserved and fixed in formaldehyde. When samples were preserved by quick-freezing in liquid nitrogen and then fixed with osmium tetraoxide in acetone, no demilunes are found.

- The posterior ligament of the head of the fibula (Fig. 348) is a single thick and broad band, which passes obliquely upward from the back of the head of the fibula to the back of the lateral condyle of the tibia. It is covered by the tendon of the Popliteus.

Cricothyroidotomy Fascia and Ligament. The thyroid gland is ensheathed by the visceral fascia, a division of the middle layer of deep cervical fascia, which attaches it firmly to the laryngoskeleton. The anterior suspensory ligament extends from the superior-medial aspect of each thyroid lobe to the cricoid and thyroid cartilage.The posteromedial aspect of the gland is attached to the side of the cricoid cartilage, first and second tracheal ring, by the posterior suspensory ligament (ie, Berry ligament).he anterior suspensory ligament extends from the superior-medial aspect of each thyroid lobe to the cricoid and thyroid cartilage.

What is the function of the chordae tendinae and the papillary muscles? The chordae tendinae connect the bicuspid and tricuspid valves to the papillary muscles. the tendinae keep the valves shut during systole. During diastole, when the chambers f … ill with blood, the papillary muscles contract, pulling the tendinae, thus opening the valves.

- Suspensory Ligament Release. The male penis consists of a “visible” and an “invisible” part; the foremost “outside” part of the male genital (what is commonly referred to as the “penis”) and the “inside” part of the male genital which is buried inside the suprapubic area.he suspensory ligament release must be followed by an intensive stretching and/or weight regimen in order to allow the penile skin and the ligaments to stretch further and prevent a retraction and scarring of the severed suspensory ligaments.

Cranial sutures and fontanels Cranial sutures and fontanels. Joints called cranial sutures, made of strong, fibrous tissue, hold the bones of your baby's skull together until the bones fuse, normally around age 2. Until then, the sutures intersect at the fontanels, the soft spots on your baby's head. The largest of the four fontanels is at the front of the skull (anterior).

- … The function of these valves is to prevent backflow of blood (back into the atria), when the muscles (papillary muscles) attached to the valves contract following diastole (which is the relaxation of the heart -simply put-). When these valves close, systole (which is the contraction of the ventricles) occurs.

Ligament Ligaments are similar to tendons and fasciae as they are all made of connective tissue. The differences in them are in the connections that they make; ligaments connect one bone to another bone, tendons connect muscle to bone and fasciae connect muscles to other muscles.n anatomy, a ligament is the fibrous connective tissue that connects bones to other bones and is also known as articular ligament, articular larua, fibrous ligament, or true ligament. Ligament can also refer to: 1  Peritoneal ligament: a fold of peritoneum or other membranes.

Medical Definition of Ciliary muscle Ciliary muscle: A circular muscle that relaxes or tightens the zonules to enable the lens to change shape for focusing.The zonules are fibers that hold the lens suspended in position and enable it to change shape during accommodation.iliary muscle: A circular muscle that relaxes or tightens the zonules to enable the lens to change shape for focusing.

The Extraocular Muscles Look again at the graphic of the right eye in the section above. If the superior rectus (SR) muscle of the eye were to be contracted with no other muscles in play, it can be visualized how the front of the eye would be pulled upward (supraduction or elevation) and inward (adduction), toward the top of the nose.ith the left eye looking to the right, if the IO muscle also were to contract, the front of this eye would move upward as well. Both eyes then would be looking up and to the right. This yoked or conjugate movement of these two muscles, right SR and left IO, is depicted in the first (top/left) image of the chart above.

About the Eye and How It Works The ciliary muscles, which are part of the ciliary body, are attached to the lens and contract or release to change the lens shape and curvature. The lens becomes more rounded to focus on near objects (see Figure 1): Fig. 1: A more rounded lens can focus on near objects.

The occipitofrontalis muscle moves up the scalp and eyebrows. The muscle has a frontal belly and an occipital (near the occipital bone on the posterior part of the skull) belly.
