Do synovial joints have elastic cartilage?
The bones of a synovial joint are covered by a layer of hyaline cartilage that lines the epiphyses of joint ends of bone with a smooth, slippery surface that does not bind them together. This articular cartilage functions to absorb shock and reduce friction during movement.
What is the function of the synovial membrane in a synovial joint?
A layer of connective tissue that lines the cavities of joints, tendon sheaths, and bursae (fluid-filled sacs between tendons and bones). The synovial membrane makes synovial fluid, which has a lubricating function.
What are the 3 capsular ligaments?
The hip joint itself is reinforced by 3 primary fibrous capsular ligaments (iliofemoral, ischiofemoral, and pubofemoral), and each serves distinct functional roles to stabilize the joint 5 , 8.
What does capsular mean in medical terms?
(kăp′səl, -so͞ol) 1. A small soluble container, usually made of gelatin, that encloses a dose of an oral medicine or a vitamin. 2. Anatomy A fibrous, membranous, or fatty sheath that encloses an organ or part, such as the sac surrounding the kidney or the fibrous tissues that surround a joint.
What joints have elastic cartilage?
Elastic cartilage occurs in the external ear, corniculate cartilages, epiglottis and apices of the arytenoids. Like hyaline cartilage, it contains typical chondrocytes, either singly or in small groups, surrounded by a matrix rich in type II collagen fibrils.
What joints contain elastic cartilage?
Fibrous cartilage has many collagen fibers and is found in the intervertebral discs and pubic symphysis. Elastic cartilage is springy, yellow, and elastic and is found in the internal support of the external ear and in the epiglottis.
What does a synovial membrane secretes?
Synovial membranes secrete synovial fluid into the joint cavity, and this lubricates the cartilage on the ends of the bones so that they can move freely and without friction.
What is the role of the synovial fluid?
The principal role of synovial fluid is to reduce friction between the articular cartilages of synovial joints during movement.
What are the 3 parts of deep fascia?
The deep fasciae envelop all bone (periosteum and endosteum); cartilage (perichondrium), and blood vessels (tunica externa) and become specialized in muscles (epimysium, perimysium, and endomysium) and nerves (epineurium, perineurium, and endoneurium).
