1. The bone is a highly vascularized connective tissue. The skeletal vasculature plays a significant role in bone development, regeneration and remodeling. This then leads to the development, regeneration and remodeling of the bone marrow which is a part of the bone and a site of blood cell production as one of its main importance. The blood cells of the body are the red blood cells(erythrocytes), white blood cells(leukocytes), and the platelets(thrombocytes). They are all important and they for the immune system. The leukocytes are the most important during this pandemic cause they help fight the virus alongside the medications administered to the patient. So without the vasculature, the immune system can’t be formed properly.
2. The subsatorial canal is also known as the adductor canal, serves as a passage way for structures moving between anterior thigh and posterior leg , the femoral artery and vein pass through this canal and give rise to the popliteal artery and vein in the distal lower limb , it also houses the saphenous nerve being the largest cutaneous branch of the femoral nerve . Adductor canal block is medical procedure in which local anaesthetic is administered in the adductor canal to block the saphenous nerve in isolation or together with the nerve to the vastus medialis . This procedure is used to provide sensory anaesthesia for procedures involving the distal thighs and femur, knee and the lower leg on the medial side, the femoral artery is used as a landmark to locate the adductor canal. Other procedures such as saphenous vein cutdown or orthopedic surgery that includes incisions or dissection over the distal tibia or medial malleolus can result in damage to the saphenous nerve, resulting in loss of cutaneous sensation in the medial leg. This is due to the intimate path that the saphenous nerve and the great saphenous vein travel. The saphenous nerve is also often damaged during vein harvest for bypass surgery and during trocar placement during knee arthroscopy. Adductor canal syndrome is a conditioning where the neurovasculsr bundle in the canal experiences an entrapment it is a rare condition mostly common to young men usually caused by hypertrophy of adjacent muscles that is , from exercises involving quadriceps muscles or prolonged walking or standing . The patient may present with claudication symptoms due to femoral artery occlusions or neurological symptoms due to entrapment of saphenous nerve.
3. A.The extraocular muscles are the 6 muscles that control movements of the eye and one muscle that controls the eyelid elevation. The actions of the muscles are responsible for eye movement depending on the position of the eye at the time of muscle contraction. The oculomotor nerve inervates the superior rectus muscle, inferior rectus muscle, medial rectus muscle, inferior oblique muscle, and the Levator palpebrae superioris muscle. The trochlear nerve inervates the superior oblique muscle. The abducens nerve inervates the lateral rectus muscle.
B. the intraocular muscles are capillary muscles inside the eyes for constricting pupils and for increasing power of lenses.
