What are the joints of the upper limb

By Emily Phillips

The upper limb has a wide range of precise movements associated with it to allow us to effectively interact with our environment, the 6 main joints covered here (from proximal to distal) are the sternoclavicular, acromioclavicular, shoulder, elbow, radioulnar, and wrist joints.

What is the upper arm joint?

The shoulder joint is formed where the humerus (upper arm bone) fits into the scapula (shoulder blade), like a ball and socket. Other important bones in the shoulder include: The acromion is a bony projection off the scapula. The clavicle (collarbone) meets the acromion in the acromioclavicular joint.

What are the 4 main joints of the shoulder?

Four joints are present in the shoulder: the sternoclavicular (SC), acromioclavicular (AC), and scapulothoracic joints, and glenohumeral joint.

What are the 5 joints of the shoulder?

  • 3.2 Acromioclavicular joint.
  • 3.3 Sternoclavicular Joint.
  • 3.4 Scapulothoracic Joint.

  • 3.6 Soft Tissue (Static & Dynamic)

What are the 3 basic types of joints?

  • synarthroses (immovable)
  • amphiarthroses (slightly movable)
  • diarthroses (freely movable)

What are the 8 major joints of the body?

These joints can be described as planar, hinge, pivot, condyloid, saddle, or ball-and-socket joints. Figure 3. Different types of joints allow different types of movement. Planar, hinge, pivot, condyloid, saddle, and ball-and-socket are all types of synovial joints.

What is the hip joint called?

The hip joint is a “ball and socket” joint. The “ball” is known anatomically as the femoral head; the “socket” is part of the pelvis known as the acetabulum. Both the femoral head and the acetabulum are coated with articular cartilage.

What are the 3 shoulder joints?

The shoulder is made up of three bones: the scapula (shoulder blade), clavicle (collarbone) and humerus (upper arm bone). Two joints in the shoulder allow it to move: the acromioclavicular joint, where the highest point of the scapula (acromion) meets the clavicle, and the glenohumeral joint.

What's the shoulder joint?

The glenohumeral joint, also known as the shoulder joint, is a ball-and-socket joint that connects the upper arm to the shoulder blade. This joint allows free movement of the arm so that it can rotate in a circular fashion.

How many joints are in the arm?

It’s actually comprised of three different bones and three different joints. Three bones meet at the elbow: Humerus: The arm’s largest bone, it joins with and connects to the clavicle and shoulder.

What is the top of the shoulder called?

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.

What is sternoclavicular joint?

The sternoclavicular (SC) joint is one of the four joints that complete the shoulder. The joint is located in the spot where the clavicle (collarbone) meets the sternum (breastbone) at the base of the neck. Although not common, problems with the SC joint can arise from injury and other disorders.

What is the joint of shoulder and hips called?

The socket of the shoulder is called the glenoid and that of the hip is referred to as the acetabulum. The labrum in the shoulder is responsible for acting as a “bumper” that the ligaments connect to and aid in stability of the shoulder.

What are the 4 types of joints?

  • Ball-and-socket joints. Ball-and-socket joints, such as the shoulder and hip joints, allow backward, forward, sideways, and rotating movements.
  • Hinge joints. …
  • Pivot joints. …
  • Ellipsoidal joints.

What are the 6 major joints of the body?

The six types of synovial joints are pivot, hinge, condyloid, saddle, plane, and ball-and socket-joints (Figure 9.4.

What kind of joint is at shoulder and knee?

The third functional class of joints is the freely movable diarthrosis joints. Diarthroses have the highest range of motion of any joint and include the elbow, knee, shoulder, and wrist.

What are joints and types of joints?

There are three types of joints in the structural classification: fibrous, cartilaginous, and synovial joints. Fibrous joints are joints in which bones are joined by dense connective tissue that is rich in collagen fibers. These joints are also called sutures.

What is joints and its types?

Joints aka articular surface can be defined as a point where two or more bones are connected in a human skeletal system. Cartilage is a type of tissue which keeps two adjacent bones to come in contact (or articulate) with each other. 3 Types of joints are Synovial Joints, Fibrous Joints, and Cartilaginous Joints.

What is the knee joint called?

The knee, also known as the tibiofemoral joint, is a synovial hinge joint formed between three bones: the femur, tibia, and patella.

What is the ankle joint called?

The ankle joint, or Talocrural joint, is a large synovial joint. It is a hinge joint that allows plantarflexion and dorsiflexion, moving the foot up and down. The ankle is more stable while joint is in dorsiflexion, and the anterior part of the talus is held in the joint.

What are the three joints of the hip and pelvis?

The hip joint is the junction where the hip joins the leg to the trunk of the body. It is comprised of two bones: the thighbone or femur, and the pelvis, which is made up of three bones called ilium, ischium and pubis. The ball of the hip joint is made by the femoral head while the socket is formed by the acetabulum.

What is the wrist joint called?

The wrist joint also referred to as the radiocarpal joint is a condyloid synovial joint of the distal upper limb that connects and serves as a transition point between the forearm and hand. A condyloid joint is a modified ball and socket joint that allows for flexion, extension, abduction, and adduction movements.

What is the arm joint called?

The arm in the human body is made up of three bones that join together to form a hinge joint called the elbow. The upper arm bone or humerus connects from the shoulder to the elbow forming the top of the hinge joint. The lower arm or forearm consists of two bones, the radius and the ulna.

How many bones are in your upper limb?

Upper extremity bones: The 64 upper extremity bones consist of 10 shoulder and arm, 16 wrist and 38 hand bones. The 10 shoulder and arm bones are the clavicle, scapula, humerus, radius, and ulna on each side.

What type of joint is the glenohumeral joint?

The glenohumeral joint is structurally a ball-and-socket joint and functionally is considered a diarthrodial, multiaxial, joint. [1] The glenohumeral articulation involves the humeral head with the glenoid cavity of the scapula, and it represents the major articulation of the shoulder girdle.

What is a joint?

Joints are where two bones meet. They make the skeleton flexible — without them, movement would be impossible. Joints allow our bodies to move in many ways.

What type of joint is the SC joint?

The sternoclavicular (SC) joint is a saddle-shaped, synovial joint that serves as the primary skeletal connection between the axial skeleton and the upper limb.

What are synovial joints?

Synovial joints are the most common type of joint in the body (see image 1). These joints are termed diarthroses, meaning they are freely mobile. … The articular cartilage and the synovial membrane are continuous. A few synovial joints of the body have a fibrocartilage structure located between the articulating bones.

What type of joint is the first Sternocostal joint?

The first sternocostal joint is an unusual type of synarthrosis (fibrous joint) and is often inaccurately called a synchondrosis. The second to seventh sternocostal joints are synovial, although articular cavities are often absent, particularly in the lower joints.

What are the two types of joints that involve the sternum?
