Questions: Muscular tissue consists of what type of cells or fibers? Multiple Choice Elongated fibers (cells) that are specialized to contract Elongated fibers (cells) surrounded by abundant matrix Cells with multiple processes that are specialized to send electrical signals Collagen fibers that conduct electrical impulses and contract Spherical cells designed for storage

The answer is the first one: Elongated fibers (cells) that are specialized to contract.

Explanation for each option:

1. Elongated fibers (cells) that are specialized to contract: This is correct. Muscular tissue is composed of elongated cells known as muscle fibers, which have the unique ability to contract and generate force. This property is essential for movement and various bodily functions.

2. Elongated fibers (cells) surrounded by abundant matrix: This is incorrect. While some tissues, like connective tissue, have cells surrounded by an abundant extracellular matrix, muscle tissue is characterized by its elongated fibers that are specialized for contraction, not by an abundant matrix.

3. Cells with multiple processes that are specialized to send electrical signals: This is incorrect. This description fits neurons, which are specialized for transmitting electrical signals, not muscle cells.

4. Collagen fibers that conduct electrical impulses and contract: This is incorrect. Collagen fibers are a component of connective tissue and do not have the ability to conduct electrical impulses or contract. Muscle fibers, not collagen fibers, are responsible for contraction.

5. Spherical cells designed for storage: This is incorrect. Spherical cells designed for storage are typically found in adipose tissue (fat cells), not in muscular tissue.

Summary: Muscular tissue consists of elongated fibers (cells) that are specialized to contract, enabling movement and various bodily functions.
