The Shoulder Joint Fig 1.0 – The articulating surfaces of the shoulder joint. The shoulder joint is formed by the articulation of the head of the humerus with the glenoid cavity (or fossa) of the scapula. This gives rise to the alternate name for the shoulder joint – the glenohumeral joint. Type of joint – It is a ball and socket joint. 2  Bony surfaces – Shallow glenoid cavity and large humeral head – there is a 1:4 disproportion in surfaces. 3  A commonly used analogy is the golf ball and tee. 4  Laxity of the joint capsule.

Temporomandibular joint The part of the mandible which mates to the under-surface of the disc is the condyle and the part of the temporal bone which mates to the upper surface of the disk is the articular fossa or glenoid fossa or mandibular fossa. The articular disc is a fibrous extension of the capsule in between the two bones of the joint.ach TMJ is classed as a ginglymoarthrodial joint since it is both a ginglymus (hinging joint) and an arthrodial (sliding) joint. The condyle of the mandible articulates with the temporal bone in the mandibular fossa. The mandibular fossa is a concave depression in the squamous portion of the temporal bone.

Anatomy With this tool, they have been able to identify and treat a shoulder injury called a glenoid labrum tear. The shoulder joint has three bones: the shoulder blade (scapula), the collarbone (clavicle), and the upper arm bone (humerus). The head of the upper arm bone (humeral head) rests in a shallow socket in the shoulder blade called the glenoid. The head of the upper arm bone is usually much larger than the socket, and a soft fibrous tissue rim called the labrum surrounds the socket to help stabilize the joint. The rim deepens the socket by up to 50% so that the head of the upper arm bone fits better.

Padova Travel Guide Palazzo Della Ragione. The Ragione sits in the center of old Padova, between the Piazzas delle Erbe and delle Frutta. These piazzas are often full of vedors, but sometimes there is a clear view of the grand old building. Once inside you can explore the almost 100 foot long interior hall, which is full of frescos and artifacts.

- -Locate the glenoid fossa (where the humerus and the scapula articulate-ie, make a joint), it faces laterally. Clavicle-The clavicle’s flat end articulates with the acromion of the scapula and the knobbed end articulates with the sternum. It is somewhat s-shaped and the medial half is convex anteriorly and the lateral half is concave anteriorly.

Shoulder The shoulder joint (also known as the glenohumeral joint) is the main joint of the shoulder. It is a ball and socket joint that allows the arm to rotate in a circular fashion or to hinge out and up away from the body.here are two kinds of cartilage in the joint. The first type is the white hyaline cartilage on the ends of the bones (called articular cartilage) which allows the bones to glide and move on each other. When this type of cartilage starts to wear out (a process called arthritis), the joint becomes painful and stiff.

- The shoulder joint is made up of bones held in place by muscles, tendons, and ligaments. Tendons are tough cords of tissue that hold the shoulder muscles to bones. They help the muscles move the shoulder. Ligaments hold the three shoulder bones to each other and help make the shoulder joint stable.

The Shoulder: Anatomy and Normal Range of Motion The shoulder is made up of three bones: the upper arm bone (humerus), the shoulder blade (scapula) and the collarbone (clavicle). These bones are joined together by muscles, ligaments and tendons that support and stabilize the shoulder, allowing the arm to function.The shoulder is composed of four joints:1  The glenohumeral joint is the main joint of the shoulder. 2  It is where the rounded top part of the arm bone, the humeral head or ball, meets the socket (glenoid) of the shoulder blade. 3  This joint is referred to as a ball and socket joint in terms of its shape and function.he shoulder is made up of three bones: the upper arm bone (humerus), the shoulder blade (scapula) and the collarbone (clavicle).

Bones & Joints of the Shoulder This articulation between the acromial end of the clavicle and the acromion of the scapula forms the roof of the shoulder. The scapula is a large, flat triangular bone with three processes called the acromion, spine and coracoid process.

Synovial joint Synovial joint. A synovial joint, also known as diarthrosis, joins bones with a fibrous joint capsule that is continuous with the periosteum of the joined bones, constitutes the outer boundary of a synovial cavity, and surrounds the bones' articulating surfaces. The synovial cavity/joint is filled with synovial fluid. The joint capsule is made up of an outer layer, the articular capsule, which keeps the bones together structurally, and an inner layer, the synovial membrane, which seals in the synovial fluid. They are the most common and most movable type of joint in the body of a mammal.

SYNOVIAL JOINTS: This fluid is composed of mucopolysaccharides, is highly viscousand slippery and reduces friction. The joint cavityis enclosed by a double layered membrane: the articular capsule. The outer layeris a tough membrane of collagen fibers(dense irregular connective tissue proper) which is firmly attachedto the surface of the boneson either side of the joint.

Synovial Joints The main structural differences between synovial and fibrous joints are the existence of capsules surrounding the articulating surfaces of a synovial joint and the presence of lubricating synovial fluid within those capsules (synovial cavities). Articular cartilage: the bones of a synovial joint are covered by this layer of hyaline cartilage that lines the epiphyses of joint end of bone with a smooth, slippery surface that does not bind them together; articular cartilage functions to absorb shock and reduce friction during movement.

Shoulder The shoulder consists of a ball-and-socket joint formed by the humerus and scapula and their surrounding structures - ligaments, muscles, tendons - which support the bones and maintain the relationship of one to another.

Mandibular fossa The temporomandibular joint is a synovial joint where the head of the mandible articulates with the mandibular fossa (glenoid fossa) and the articular eminence of the temporal bone. The articular surfaces of this joint are covered by fibrocartilage (not hyaline) and there is also a fibrocartilaginous articular disc dividing the joint cavity into upper and lower compartments.

Anatomy Your shoulder is made up of three bones: your upper arm bone (humerus), your shoulder blade (scapula), and your collarbone (clavicle). The head of your upper arm bone fits into a rounded socket in your shoulder blade. This socket is called the glenoid.

Bones & Joints of the Shoulder Bones & Joints of the Shoulder. The bones of the shoulder consist of the humerus (the upper arm bone), the scapula (the shoulder blade), and the clavicle (the collar bone). The clavicle is the only bony attachment between the trunk and the upper limb. It forms the front portion of the shoulder girdle and is palpable along its entire length with a gentle S-shaped contour.The clavicle articulates at one end with the sternum (chest bone) and with the acromion of the scapula at the other.

The Shoulder The shoulder includes the proximal humerus, the clavicle and the scapula, and their connections to each other, to the sternum (clavicle), and to the thoracic rib cage (scapula). Together, these elements form the most mobile joint in the human body (Figure 1).

What is articular cartilage? Home → Articular Cartilage Tear Information. Articular cartilage, also known as hyaline cartilage, is a very smooth yet hard material made up of the protein collagen. The cartilage is located on a bone’s articulating surfaces (surfaces of a bone that come in contact with other bones). It allows for the smooth interaction between two bones in a joint.

Synovial Joints Also unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly against each other, allowing for increased joint mobility.tructural Features of Synovial Joints. Synovial joints are characterized by the presence of a joint cavity. The walls of this space are formed by the articular capsule, a fibrous connective tissue structure that is attached to each bone just outside the area of the bone’s articulating surface.
