g. From the Synovial Joint page, click structural subtypes of synovial joints. Locate body examples of the following joints and describe the movement of each. Condyloid: This is an oval shopped articulating surface where one bone fits into a depression of another bone. Planar: This is a plane joint with no axil in which the articular surface is flat or only slightly curved. This allows slipping or gliding movements.
All bones give attachment to muscles, which are responsible for 50% of our body weight and also permit movement. Bones are moved at joints by contraction and relaxation of the muscles attached to them. The spine is the major supporting structure of the body. It is a flexible column made up of 24 true or moveable vertebrae, and 9 false or fixed vertebrae closely fused to form the sacrum and the coccyx with no movement ( except the coccyx which moves in relation to the sacrum) The individual vertebrae differ in shape and size, according to which area they are found in and the particular functions they perform. The vertebral column forms a stable but mobile axis for the rest of the body.
Module 06 Case Study: Articulations and Nerve Tissue Part I— “Jill” Questions 1. What is the difference between a tendon and ligament? (1 point) Tendons bind muscle to bone, and ligaments bind bone to bone. A sprain is an extended and/or torn ligament, the band of connective tissue that connects the end of one bone with another bone. Ligaments support and stabalize the an individuals joints.
A)long B)irregular C)short D)flat Feedback: Correct! 3 CORRECT A bone that is cuboidal in shape is a ________________ bone. A)long B)short C)flat D)irregular Feedback: Correct! 7.2 Histology of Osseous Tissue 4 CORRECT Which of the following is a mature bone cell that appears to be responsible for the overall supervision of bone maintenance? A)osteogenic cells B)osteoblasts C)osteocytes D)endosteum cells E)osteoclasts Feedback: Correct!
In the periosteum it surrounds the bone surface wherever it is not covered by articular cartilage, it is a sheath of dense irregular connective tissue containing osteoblasts, it functions to protect the bone, assists in fracture repair, nourishes bone tissue, and serves as an attachment point for ligaments and tendons. 4- Which kind of bone marrow is in spongy bone tissue? Red bone marrow is the type of marrow found in spongy bone tissue. 5- Which ossification method would form a femur? Endochondrial ossification would form the femur.
Describe the function of a ligament and of a tendon. -Fasciae are the fibrous connective tissue sheets that wrap around muscle bundles to hold them in place. Ligaments are strong, flexible bands (or cords) that hold bones firmly together at the joints. Tendons are white, glistening bands that attach skeletal muscles to the bones. 5.)
The human skeleton Is made up of 206 bones. The functions of the skeleton are to provide support, give our bodies shape, and provide protection to other systems and organs of the body, to provide attachments for muscles, to produce movement Joints A joint is the point where two or more bones meet. There are three main types of joints; Fibrous (immoveable), Cartilagenous (partially moveable) and the Synovial (freely moveable) joint. Fibrous joints Fibrous (synarthrodial): This type of joint is held together by only a ligament. Examples are where the teeth are held to their bony sockets and at both the radioulnar and tibiofibular joints.
Turn the wing upside down and bend the joints. Again pull on each muscle and note how the bones move. Locate the nerve and blood vessels along the biceps muscle. Locate where the biceps muscle attaches to the bones. Pull on the muscle again and try to recognize what is happening to the bones.
The vertebral column is a structure of bone that is located in the back that encases the spinal cord from top to bottom in order to protect it from injury. The brain is protected by a series of bone,
