6 Bones and Skeletal • Human skeleton is initially made up of cartilages and fibrous membranes as early supports – These are replaced by bone as we grow – The cartilages found in adults are in places where flexible skeletal tissue is needed Skeletal Cartilages • Contain no _______ ________ or ______, and consist mainly of water • Dense irregular connective tissue girdle of perichondrium (around the cartilage) contains blood vessels for nutrient delivery to cartilage – Nutrients diffuse through the matrix to reach the cartilage cells Skeletal Cartilages 1. Hyaline cartilages – Provide: support, flexibility, and resilience – Most abundant type – 1. Articular cartilages- covers the ends of bones and moveable joints – 2. Costal cartilages – 3. Respiratory cartilages- form the skeleton of the larynx – 4.…
The ends of bones that form joints with adjacent bones are called the _ epiphyses _.…
Ligaments - Ligaments connect bones to other bones at joints. They look like a shiny white covering of the joint surfaces.…
have variety of shapes and are usually connected to several other bonesEx. vertebrae, many facial bones…
A synovial joint also known as diarthrosis, joins bones with a fibrous joint capsule. It is continuous with the periosteum of the joined bones, constitutes the outer boundary of a synovial cavity, and surrounds the bone articular capsule. The articular capsule keeps the bones together structurally, and an inner layer, the synovial membrane, which seals the synovial fluid. Synovial cavity all diarthroses have the characteristic spaces between the bones that is filled with synovial fluid. Joint capsule the fibrous capsule surrounds the diarthrosis and unites the articulating bones. The joint capsule consists of two layers. The outer fibrous membrane that contains ligaments and the inner synovial membrane that secretes the lubricating, shock absorbing,…
This system is constructed of bones such as, joints, tendons, ligaments, skeletal muscles, nerves, cartilage, hyaline cartilage, elastic cartilage and fibrocartilage. There are five main functions of the bones, these include:…
epiphyseal plate: located in the metaphysis, composed of hyaline cartilage, is the growth plate; articular cartilage: covers the part of the epiphysis where the bone forms an articulation with another bone, composed of hyaline cartilage, reduces fiction and absorbs shock at freely movable joints; periosteum: surrounds the bone surface wherever it is not covered by articular cartilage, is a sheath of dense irregular connective tissue containing osteoblasts, functions to protect the bone, assists in fracture repair, nourishes bone tissue, and serve as an attachment point for ligaments and tendons…
o Most fibrous joints are immovable o Sutures have very short CT fibers o In syndesmosis the bones are connected by a ligament A few notes about cartilaginous joints: o…
10. What are sutures (of the skeletal system) and give 2 examples? Sutures are the joints between the bones of the skull. There is the Coronal suture and the Squamous suture.…
* Cartilage- Allows bones to move freely over one another. This stops friction occurring and the degeneration of the bone. (found in small sacs called Bursa)…

Ligaments are the strong connective tissues that connect bones with one another. They are located immediately over the bones and discs originate and innervate with vertebrae and function to limit the movement of one…
Bricks in a building must be stuck together and also tied somehow to the foundation. Similarly, cells within tissues and organs must be anchored to one another and attached to components of the extracellular matrix.…
