Please answer the following questions

Answer 1

18) e) More than one of the above

The answers are right internal thoracic vein and right lymphatic duct –

The right lymphatic duct carry lymph from right upper limb to right side of thorax and head and neck whereas the thoracic duct drains the lymph in the circulatory system. The thoracic duct is collected by the duct and it drains close to the brachiocephalic vein. It drains into the subclavian vein.

19) Left superior gluteal – This nerve originates from the pelvis and helps in supporting the pelvic and hip muscles. It helps in stabilizing the pelvis in coronal plane and if there is damages to these nerves it can cause weakness of the muscles and lead to weak abduction in the hip joint.

20) c) Posterior Deltoid – The muscle is back of the deltoid of the muscle and helps in attaching the shoulder blade and helps in extending and rotating the arm laterally. It has the axillary nerve and has a number of artery which are called thoracoacromial artery, anterior and posterior artery.

Ans 21) Manubrium

The clavicle articulates and forms two bones where the medial end of the clavicle expands through the ovoid and it ends up articulating into the manubrium.
