Which type of bone provides a large, flat surface for muscle to attachment? b. A flat bone provides a large surface for muscle to attach. For example the hip bone and rib bones. 3.
The coracoacromial ligament is a strong triangular band, extending between the coracoid process and the acromion. It is attached, by its apex, to the summit of the acromion just in front of the articular surface for the clavicle; and by its broad base to the whole length of the lateral border of the coracoid process. This ligament, together with the coracoid process and the acromion, forms a vault for the
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
A thin edge of the scapula closer to the vertebral column is called the medial border. The hick edge closer to the arm is called the lateral border. The medial and lateral borders join at the inferior angle. The superior edge of the scapula called the superior border, joins the medial border at the superior angle. The proximal end of the humerus feature a rounded head that articulates with glenoid cavity of the scapula to form the shoulder joint.
174 – a) shaft of the bone, b) end of the bone, c) between the shaft and end of the bone 7. Describe the location, composition, and function of the epiphyseal plate, articular cartilage, and periosteum. Ans: pg. 174 – 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 8. Why is osseous tissue considered a connective tissue?
The exposed surface of the trabuculae is where the canaliculi ends and where nutrients and waste are diffused. 2. In general compare and contrast the three functional classifications of joints according to movement. What are two characteristics that make synovial joints unique and different from other joints? Which joint is stronger-the shoulder or hip joint and why is it?
L. Ball-and-socket joint M. Hinge joint N. Pivot joint O. Condylar joint or ellipsoidal joint Part 4: Identify the types of muscle groups on Muscle Man (e.g., facial, lower extremity, torso, upper extremity). P. temporalis, zygomaticus, splenius Q. iliacus, psoas major, rectus femoris, biceps femoris R. pectorals major, peltoid, internal, external intercostal S. trapezius, deltold, short head of bicepis brachll, and long head of bicepis brachll Part 5: Identify the type of muscle tissue on your lab report worksheet (skeletal, smooth, or cardiac). Bones and muscles are both important in their own right, but it is when the two systems work together that “the magic happens”. T. smooth Identify this tissue. U. tendons What is its function?
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.
Label the following structures of your specimen: Bicep muscle Tricep muscle Forearm muscle Tendon Part B: Straighten the chicken wing and hold it horizontally above the tray. Identify the biceps muscle and triceps muscle. The biceps muscle is on the anterior part of the upper wing; the triceps is located on the posterior part of the upper wing. Pull on each of the muscles in the upper and lower wing, and note the movement that each muscle causes. Turn the wing upside down and bend the joints.
This is called the gleniod cavity. It articulates with the humerous. On the anterior surface there is a hollowed-out are called the subscapula fossa. This is where the shoulder muscle attaches to. 1.
