Anatomy Lab 4.1.docx

Activity 1 - Appendicular Skeleton 1. Study the figure above. Make a list A-H and label the parts. A: Acromioclavicular joint B: Sternoclavicular joint C: Glenohumeral joint- synovial ball and socket joint D: scapular coracoid E: coracoid process F: scapula G: Clavicle H: Humerus/Greater Tubercle 2. Study the picture. Make a list, 1-29 and label the parts. 1: Frontal Bone 2: Parietal Bone 3: Temporal Bone 4: Occipital Bone 5: Zygomatic arch 6: Maxilla 7: Mandible 8: Cervical spine 9: nasal bone 10: sternum

11: humerus 12: ulna 13: radius 14: spine 15: pelvic girdle 16: coccyx 17: hip bones 18 femur 19patella 20: Tibia 21: Fibula 22: Greater trochanter 23: Medial Condyle 24: Tibial Tuberosity 25: Clavicle 26: Coronoid fossa of the humerus 27 trochlea (elbow) 28 ribs 29 scapula Activity 2 - Bone Study For each of the bones listed, write a description of its location (name articulating bones as well as general location) in the body and its function and at least three anatomical features of each bone, describing their functions and where on the bone they are located

1. clavicle a. The clavicle lies horizontally across the anterior side of the thoracic cage and is superior to the first rib and inferior to the cervical spine. The sternal end articulates with the manubrium and the acromial end articulates with the acromion of the scapula b. Its function is to help support the shoulder. c. 3 features of the clavicle i. Conoid tubercle: serves as a point of attachment for the conoid ligament. On the inferior surface of the lateral end of the bone ii. Impression for costoclavicular ligament: serves as a point of attachment for the costoclavicular ligament. On the inferior side of the medial end of the bone. iii. Sternal end: serves as the point of attachment to the manubrium of the sternum. Located on the medial end of the bone. 2. scapula a. The scapulae (one on each side of the spine) is located on the dorsal side of the body between the locations of the 2nd and 7th ribs and attaches to the thoracic cage. It is a triangular flat bone. b. Its function is to allow for full range of motion of the arms. c. 3 features of the scapula are i. Acromion: bony projection on superior end of scapula. Acts as a connection point for muscles and helps form the acromioclavicular joint. ii. Coracoid process: process that is shaped like a hook on the lateral anterior side of the scapula. Helps to stabilize the shoulder joint. iii. Glenoid cavity: Shallow, articular surface on the lateral side of the scapula. Inferior to the coracoid process. Accepts head of the humerus and forms the shoulder joint. 3. Humerus a. The humerus is a long shaped bone of the upper arm. It has a proximal rounded head, a cylindrical body, and a flattened distal end. It articulates with the scapula proximally and distally with the ulna and radius. b. Its function is to allow for movements of the lower arm as well as serving as a point of attachment for 13 muscles. c. 3 features of the humerus
