The “spindle-shaped” or “fusiform” bodies of fibroblasts are membrane-bound collagen fibrils. These cellular organelles, also described in the literature as rods or cigars, can be induced massively in chick embryo fibroblasts by treatment with colchicine in vinblastine.
What is the meaning of spindle shape?

What is spindle shaped root?
Complete answer: The root of the radish is the modified root and is known as the fusiform root. This type of root has a tapering end part and the tapering top part. It forms a spindle-like shape.
What is a fusiform body shape?
The fusiform body shape is rounded or torpedo shaped and streamlined, which is an ideal shape for fast, continual swimming. Fish with this body shape are well adapted for feeding and survival in open water because the fusiform shape creates minimal drag as the fish swims through the water.
Why are muscle cells spindle shaped?

What is a spindle used for?
A spindle provides the twist that turns fiber into yarn. When using a hand spindle, your hands let the fibers slide past each other and then let the twist catch them, a process known as “drafting.” The size of the yarn is determined by how much fiber is caught in the twist.

What’s the best way to shape a spindle?
Do the opposite to shape the right side of a cove profile. Start with the gouge’s flute at about the 2 o’clock position. Lightly touch the tip into the spindle by lifting the tool’s handle.

Where is the spindle on a shaper blade?
Protruding vertically through the tabletop is the motor-driven shaft, or spindle, onto which blades are fastened. The workpiece is presented to the spinning blade, which cuts the stock to match the shape of the blade. Freehand work is done with the fence removed.
How are the different types of spindles different?
The various types of supported spindles range due to the difference in styles of spinning and yarn weight. Navajo spindles have longer shafts that should reach from the ground to the top of the thigh. The spun yarn is wound above the whorl. In Icelandic Viking times, the people used a high whorl lap spindle to spin wool into yarn.
