Which cell is spindle shaped cell?
Emily Dawson Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations. They are called Smooth muscle - Wikipedia
Which cells are spindle shaped?
Muscle cells are the spindle-shaped cells found in the human body. They have a spindle shape because they control the human body's contraction and relaxation. The connective tissues encircle these cells.
What is an example of spindle shaped cell?
Muscle Cell is an example of spindle (elongated) cell.
Where are spindle shaped cells found?
Smooth muscle cells are spindle shaped. These are found in stomach lining, blood vessels, urinary bladder, respiratory tract and also uterus.
Why muscle cells are spindle shaped?
Muscle cells are spindle shaped because it help them to align properly over one another and also it make easy for them to contract and relax while movement of the body parts.

Complete answer: The smooth muscle cell is a spindle-shaped muscle cell.
What is a spindle shape?
Definition. adjective. Having a shape like a spindle, that is being wide in the middle then tapering at both ends.
Is vegetative cell spindle shaped?
Vegetative cell has an irregularly shaped nucleus, and the generative cell is spindle-shaped with dense cytoplasm & nucleus. Vegetative cell is also termed as Tube cell as it is responsible for growth of pollen tube.
What is the shape of nerve cell?
Nerve cells are usually shaped like branched trees. From the round, pyramidal or spindle-shaped cell body, the dendrites branch out like the top of a tree and the single axon travels out like the trunk.
Which muscular cells are spindle shaped and Uninucleate?
Hint:The spindle-shaped, uninucleate, unbranched and involuntary cells are characteristic features of smooth muscle. There are three types of muscles in the body such as: Smooth muscle, Skeletal muscle and Cardiac muscle with its specific characteristics respectively.
Are cardiac muscle spindle shaped?
Cardiac muscle cells contract autonomously and involuntarily. Smooth muscle is involuntary. Each cell is a spindle-shaped fiber and contains a single nucleus. No striations are evident because the actin and myosin filaments do not align in the cytoplasm.
Which is an oval shaped cell?
An example of an oval shaped cell is an egg because it contains a single cell. Also an ostrich egg is the largest known cell.
Which cell is spherical in shape?
Answer: A coccus (plural cocci) is any bacterium or archaeon that has a spherical, ovoid, or generally round shape. Bacteria are categorized based on their shapes into three classes: cocci (spherical-shaped), bacillus (rod-shaped) and spirochetes (spiral-shaped) cells.
What cells are long and spindle shaped?
The spindle-shaped cells present in the human body are muscle cells. They are spindle shaped because they are responsible for the contraction and relaxation in human body. These cells are surrounded by connective tissues.
What is the shape of a cardiac muscle cell?
Viewed through a microscope, cardiac muscle cells are roughly rectangular, measuring 100–150μm by 30–40μm. Individual cardiac muscle cells are joined together at their ends by intercalated discs to form long fibers.
Which is a branched cell?
The branched cell is NEURON.
Why are nerve cells shaped?
Nerve cell shapes vary according to the number, branching and disposition of their projections or dendrites, collectively known as arborization. This determines their capacity for interacting with their environment and with other nerve cells or neurons, hence their computational ability and roles.
What is the shape of cheek cell?
Human cheek cells are roughly circular or irregular in shape. Human cheek cells are widely used to observe the cell membrane and nucleus of animal cells.
Why are muscle cells shaped the way they are?
Skeletal muscle cells are arranged in bundles of linear fibers. A single muscle cell is elongated in shape, containing within it many myofibrils. ... The elongated shape of muscle cells allows the contraction proteins to line up in an overlapping pattern that makes muscle flexing possible.
Is generative cell spindle shaped?
The generative cells, liberated from the vegetative cell cytoplasm of the pollen protoplasts, were initially spindle-shaped with two long, oppositely oriented extensions, and were surrounded by two cell membranes, one on each side of a wall of uniform thickness.
What is vegetative cell in biology?
Any of the cells of a plant or animal except the reproductive cells; a cell that does not participate in the production of gametes; somatic cells are produced from preexisting cells;.
What are spindle cells?
Spindle cells are specialized cells that are longer than they are wide. They are found both in normal, healthy tissue and in tumours. The most common type of normal spindle cell is called a fibroblast. Fibroblasts are support cells that are found in a type of connective tissue called stroma.
What is spindle shaped root?
A spindle-shaped (fusiform) root is a root that tapers at the top and at the bottom, For example the taproot of a white radish. Spindle-shaped leaf [ Botany ] Synonym: Fusiform leaf.
What are spindles?
spindle- a rounded rod, usually of wood, tapering toward each end, used in hand-spinning to twist into thread the fibers drawn from the mass on the distaff, and on which the thread is wound as it is spun.
- the rod on a spinning wheel by which the thread is twisted and on which it is wound.
