Virtually all synchondroses are synarthrotic. In symphyses the articular surface surface of the bone are covered with articular hyaline cartilage , which in turn is fused to an intervening pad, or plate of fibrocartilage, which is the main connecting material. Fibrocartilage acts as a shock absorber and permits a limited amount of movement at the joint. 3a Articulating bone: Articulating" means that the bones are moving relative to each other at a joint. The actual surfaces of the bones that might touch the other are the articulating surfaces, and the cartilage covering those surfaces is called articular cartilage.
Sprains Sprains can be a painful injury that can affect the ligament by being over stretched or torn. Ligaments connect your bones together. The ankle, knee, and wrist are the most common injury. The way a person gets a sprain is by the ligament getting stretched too far from their normal position. The purpose of having them is to keep your skeleton in its normal alignment.

JOINT | TYPE OF JOINT | Elbow | Hinge | Shoulder | Ball and Socket | Inter-Vertebral | | Knee | Hinge | Ankle | Gliding | QUESTIONS: 1. Define a joint? A joint is the location at which two or more bones make contact.
Casey Jones SPM 381 Movement Analysis Project Cartwheel A cartwheel is a sideways movement used in the gymnastic sport involving high levels of joint range of motion, flexibility, strength, and stability. Hip abduction is crucial for efficient movement. Lack of range of motion and flexibility will result in incompletion of the cartwheel itself. Using the first class lever predominantly, the motion can be divided into three phases: translation 1, straddle, and translation 2. Translation one is similar to a Romanian deadlift where one leg is stabilized with a slight bend in the knee as the arms reach towards the ground.
In addition to being flexible, each hip joint must be capable of supporting half of the body’s weight along with any other forces acting upon the body. During running and jumping, for example, the force of the body’s movements multiplies the force on the hip joint to many times the force exerted by the body’s weight. The hip joint must be able to accommodate these extreme forces repeatedly during intense physical activities. · Shoulder joint - the shoulder joint is a shallow ball-and-socket joint between the humerus - upper-arm bone - and the glenoid fossa of the scapula - shoulder blade. A unique joint, the shoulder has only one bony attachment to the rest of the skeleton in the clavicle - collarbone - where it attaches to the scapula.
Use the key terms to identify the joints described below (4 points): Key: cartilaginous fibrous synovial synovial typically allows a slight degree of movement fibrous essentially immovable joints hinge include the hip, knee, and elbow joints cartilaginous cartilage connects the bony portions Use the key terms to match the joint subcategories described below (4 points): Key: suture pivot ball and socket condyloid suture joint between most skull bones ball and socket hip joint pivot joint between the axis and atlas condyloid joint between forearm bones and wrist What characteristics do all joint have in common? (3 points) Even though some fibrous joints and some cartilaginous joints do not move, the two main characteristics of joints are to give our skeleton mobility, and to hold it together. Describe the structure and function of the following structures or tissues in relation to a synovial joint. (4 points) Ligament- Ligaments refer to a fibrous tissue that connects bones to other bones. Capsular ligaments are a part of the articular capsule that surrounds synovial joints.
Patient Diagnosis Project : Meniscus injuries 1. Patient Diagnosis : A. Definition / Description: Meniscus tear means Injuries to the crescent-shaped cartilage pads between the two joints formed by the femur (the thigh bone) and the tibia (the shin bone). (6) The meniscus acts as a smooth surface for the joint to move on and mainly works as a weight bearing weights. [pic] Menisci can tear in many different ways.
Appendicular skeleton consists of the bones of the upper and lower extremities, including shoulder and the hip. Skeletal system includes cartilage and ligaments that join bones together at joints. 2. Compare the properties of the intercellular collagen and elastic fibers of skeletal tissue. * Describe the intracellular matrix of bone and
The movement of the bones is caused by muscles which pull on tendons that are attached to bone. Cartilage is a hard, smooth tissue that covers the end of bones. Between the cartilages of two bones which form a joint, there is a small amount of thick fluid called synovial fluid. This fluid lubricates the joint which allows smooth movement between the bones. The synovial fluid is made by the synovium.
It begins to break down, leading to the formation of an ulcer. Sores often develop on the areas that take the pressure when we sit or lie down, such as the: * Hips. * Buttocks. * Base of the spine. * Heels.
