DATE: NAME: SECTION: WORKSHEET THE UPPER APPENDICULAR: SKELETAL BONEs 1. Which part of the clavicle is connected to the manubrium? 2. Identify the lateral condyle (A) and the medial condyle (8) located at the distal end of the humerus A: B: 3. Identify the anterior fossa (A) and the posterior fossa (B) located at the distal end of the humerus A: B: 4 Identify the major bulge located lateral to the olecranon process s. There is a small fossa located on the lateral edge of the ulna, which the head of the radius articulates. What is the name of that fossa?Explanation / Answer
Answer:
1) The sternal end of the clavicle via the sternal facet.
Explanation: The clavicles/collar bones are two in number and they have a sternal end, an acromial end and a shaft connecting the two.The sternal end connects to the manubrium sterni through the sternal facet which is the articulating surface. Here, It forms a joint called the sternoclavicular joint. The acromial end joins it with the acromion process of the scapula forming the acromioclavicular joint.
2) A) The lateral condyle of the distal end of the humerus has an epicondyle( projection providing attachment to muscles) and the smooth rounded eminence called the capitulum which articulates with the radius.
B) The medial condyle at the distal end of the condyle has the medial epicondyle and the trochlea which is the articular surface articulating with the ulna.
3) A) The anterior fossae located at the distal end of the humerus are the a) Radial fossa which is located superior to the capitulum and b) Coronoid fossa which is located superior to the trochlea of the humerus.
B) The posterior fossa located at the distal end of the humerus is called the olecranon fossa which receives a portion of the ulna when the arm is flexed.
5) The small fossa located on the lateral edge of the ulna,to which the head of the radius articulates is the radial notch
