Term innominate is used both in the context of a skeletal system and circulatory system. In the circulatory system, innominate is one of the branches of the aortic arch. The arch of the aorta, located immediately beyond the ascending aorta, gives off three large branches.
1. The brachiocephalic trunk is a short artery formerly called the innominate. Its name means that is supplies the head and the arm. After extending upward somewhat less than 5 cm (2 inches), it divides into the right subclavian artery, which supplies the right side of the head and the neck. 
2. The left common carotid artery extends upward from the highest part of the aortic arch. It supplies the left side of the neck and the head.
3. The left subclavian artery extends under the left collar bone (clavicle) and supplies the left upper extremity. This is the last branch of the aortic arch.
Innominate bone in anatomy refers to either of the two bones that form the sides of the pelvis, consisting of three fused components, the ilium, ischium, and pubis. The non-technical name is hip bone.

A snail uses its single long, muscular foot to crawl on a layer of mucus-like slime that it secretes. This mucus has unusual physical properties and scientists assumed that these sticky properties were essential for snail movement. 

• The skeleton is the site of haematopoiesis, the development of blood cells that takes place in the bone marrow. 
• In children, haematopoiesis occurs primarily in the marrow of the long bones such as the femur and tibia. 
• In adults, it occurs mainly in the pelvis, cranium, vertebrae, and sternum. Hence, the Skeleton is the site of Haematopoiesis.

Sesamoid bones develop in some tendons in locations where there is considerable friction, tension and physical stress. They are typically found in palm of hands and soles of feet. Therefore, (d) is the correct answer. 

1. Innominate is used to designate many parts otherwise unnamed.
   
2. Innominate artery is a great part of the arch of the aorta.
3. The innominate bone is the hip bone which is part of the skeleton system

There are usually 12 pairs of ribs in human body, first seven pairs of ribs are known as true ribs because these are attached to sternum.

Each hind limb contains 30 bones namely femur in thigh, patella inthe knee, tibia and fibula in the lower leg, 7 tarsals in the ankle, 5 meta-tarsals in the sole and 14 phalanges in toes.

• Hindlimb is composed of  Femur (thigh bone – the longest bone), tibia and fibula, tarsals (ankle bones – 7 in number), metatarsals (5 in number) and phalanges (digits – 14 in number).
  
• When a cricket player is chasing a ball it represents he is running. during running hind limbs assist motion hence muscles off hind limbs contribute to the motion.
  
• Hence when a cricket player is chasing a ball. the group of muscles which contribute to this movement are tarsals, femur, metatarsals, tibia.
• So, the correct answer is 'Tarsals, femur, metatarsals, tibia'.

• The osteon or Haversian system is the fundamental functional unit of much compact bone. 
• Osteons are roughly cylindrical structures. 
• Presence of the Haversian system is a typical character of mammalian bone. Panther is a mammal. Hence, bones of panther shall have a Haversian system.
