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.
-tendons attach muscles to the bones - cartilage protects bones within joints. - synovial fluid: acts as lubricant - synovial membrane: secretes synovial fluid - ligament: joins bone to bone and is strong and flexible - muscle - fibrous capsule: encloses joints - pad of cartilage: gives additional protection - cartilage: absorbs synovial fluid and acts as shock absorber - bone - tendon: joins muscle to bone At a joint there is: Joints and movement continued 2 of 60 1 of 60 How do muscles work? - muscle is made up of bundles of muscle fibres, each fibre is a single muscle cell - each muscle cell is multinucleate (has more than one nucleus) this is because a single nucleus could not effectively control the metabolism of such a long cell. - Tendons connect muscle to bone - the muscle is made up of bundles of muscle fibres. these are bound together by connective tissue.
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.
• Be sure you know the root words and their meanings • Name and describe the three connective tissue layers found in a muscle: These layers allow parts to move on their own and also provide and area for blood vessels and nerves to move through. o Epimysium: The epimysium closely surrounds skeletal muscles. o Perimysium: This connective tissue divides muscle tissue into little segments. o Endomysium: This is a thin covering that houses bundles of muscle fibers called fascicles. • Define: antagonist, synergist, prime mover o Synergist: a muscle that assists the action of a prime mover o Antagonist: A muscle that act in opposition to a prime mover o Prime Mover: muscle primarily responsible for producing an action • List the various ways that muscles are named.
| Muscular System | |The Muscles: Each muscle is an organ, comprised of skeletal __muscle__ tissue, several ___connective____ tissue coverings, __nervous_ tissue to cause it | |to contract, and __blood___ to nourish it. | | Connective Tissue coverings: | |The muscle has several dense connective coverings.
It is controlled by two muscles, the biceps on the front of the upper arm, and the triceps on the back of the upper arm. The biceps and the triceps are antagonistic muscles. This is when the biceps muscle contracts, the forearm moves up and when the triceps muscle contracts, the forearm moves down. Synergist: The synergist in a movement is the muscle’s that stabilises a joint around which movement is occurring, which in turn helps the agonist function effectively. Synergist muscles also help to create the movement.
Definition: Bones are rigid organs that constitute part of the endoskeleton of vertebrates. They support and protect the various organs of the body, produce red and white blood cells and store minerals. Bone tissue is a type of dense connective tissue. Bones come in a variety of shapes and have a complex internal and external structure, are lightweight yet strong and hard, and serve multiple functions. One of the types of tissue that makes up bone is the mineralized osseous tissue, also called bone tissue, that gives it rigidity and a coral-like three-dimensional internal structure.
It plays the most important role in the extensor mechanism of the knee joint (3). The quadriceps tendons and patellar tendons link up with patella to serve the function. Extension of knee can be achieved by the tension between quadriceps and patella. Flexion of knee is limited by the quadriceps tendon. As a whole structure, patella becomes a pulley to generate force between patella-femoral joint in order to support the body against gravity
The Muscle Anatomy (http://anatomy.askthetrainer.com/) The Skeleton system (http://www.faqs.org/health/Body-by-Design-V2/The-Skeletal-System-Design-parts-of-the-skeletal-system.html) Nerve fibres run all the way through the body and send impulses to muscles, which enable the muscles to contract and relax. Nerve fibres are delicate structures and can easily become damaged through poor moving and handling techniques.

These rods are connected at their base by the plantar fascia. When force is applied to the apex of the MLA, the arch depresses and the two rods separate then the tension is distributed throughout the plantar fascia. The main ligaments that aid in supporting the MLA are the long and short plantar ligaments and the calcaneonavicular ligament.
