BY JACOB WOODS 12G Synovial Joints Synovial joints are characterised by a layer of synovial fluid surrounding the articulating surfaces. This helps to lubricate the cartilage therefore reducing the friction between the joints. The synovial capsule stores the fluid‚ meaning it can lubricate the joint quickly. There are 5 types of synovial joint. They are as follows. Ball and socket joint Spheroidal joints to give them their technical name are joints that include two articular surfaces; a ball

Muscle Contractions By: Evan Contractions‚ put simply‚ are the basic action of any muscle. A contraction is a change in a muscle by which it becomes thickened and shortened after the brain sends signals to nerve cells telling them do contract a specific muscle or muscles. Surprisingly‚ a contraction is a complex human action and reaction‚ yet it is such a breeze to understand the basic meaning of the word. Throughout this essay I will give you extensive details about the process of muscle contractions

Pivot joint: A rounded portion of a bone is enclosed within a ring formed partially by the articulation with another bone and partially by a ligament . The bone rotates within this ring. Since the rotation is around a single axis‚ pivot joints are functionally classified as a uniaxial diarthrosis type of joint. An example of a pivot joint is the atlantoaxial joint‚ found between the C1 (atlas) and C2 (axis) vertebrae. Here‚ the upward projecting dens of the axis articulates with the inner aspect

I relate to her story in so many ways‚ my mother is also a very hardworking immigrant who has done everything to give my brothers and me a better future. Mah works at sweatshop

Types of joints: Ball-and-socket joint: Consists of a bone with a globular or slightly egg-shaped head that articulates with the cup-shaped cavity of another bone. Such a joint allows a wider range of motion than does any other kind‚ permitting movements in all planes‚ as well as rotational movement around a central axis. The hip and shoulder contain joints of this type. Condyloid joint: The ovoid condyle of one bone fits into the elliptical cavity of another bone‚ as in the joints between the

composition of bone mostly consist of inorganic material and collagen fibers. The macroscopic structures of bone is Compact bone‚ Cancellous bone‚ Epiphysis‚ Diaphysis‚ Periosteum‚ Red bone marrow‚ yellow bone marrow‚ and the articular cartilage (Doitpoms.com). Collagen is a triple helix structured protein that is the most prominent protein in the skeletal system. Bones consist of two distinct types of bone tissue such as cancellous and cortical bone. Cancellous bone is also known as spongy bone and is located

Advance Preparation—ATP Muscle Kit 1. Order the ATP muscle kits (Carolina) to be delivered no more than seven days before the lab. One kit provides generously for eight students. Extra vials of the chemical solutions can be ordered separately (Carolina) and will reduce waiting time. Just before the lab begins‚ cut the muscle bundles into 2-centimeter lengths and place in a petri dish in the accompanying glycerol. 64 Exercise 11 R E V I E W S H E E T NAME ____________________________________
