Which of the following is spindle shaped?
Smooth muscle cells Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations. They are called involuntary muscles.
Which muscle cells are spindle shaped?

Why do birds have spindle shaped body?
Explanation: Birds body is spindle shaped which provide less resistance while flying or during swimming as in case of penguins. Birds volume of the body is increased by presence of feathers compared to the weight. Fore limbs are modified into wings for aerial locomotion.
Are cardiac muscle cells spindle shaped?
Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control. Smooth muscle fibers are located in walls of hollow visceral organs, except the heart, appear spindle-shaped, and are also under involuntary control.
Is spindle cell sarcoma curable?
A sarcoma is considered stage IV when it has spread to distant parts of the body. Stage IV sarcomas are rarely curable. But some patients may be cured if the main (primary) tumor and all of the areas of cancer spread (metastases) can be removed by surgery. The best success rate is when it has spread only to the lungs.
