Question
What kind of muscle has a single nucleus?
Group of answer choices
- epithelial
- smooth muscle
- nerve
- cardiac muscle
Solution
The type of muscle that has a single nucleus is smooth muscle. Here's a brief overview of the options given:
-
Epithelial: This is not a muscle tissue; it refers to layers of cells that cover the surfaces of the body and line cavities.
-
Smooth Muscle: This type of muscle tissue is involuntary and has a single, centrally located nucleus in each of its long, spindle-shaped cells.
-
Nerve: Like epithelial tissue, nerve tissue is not a type of muscle; it comprises neurons and supporting cells.
-
Cardiac Muscle: This type has a single nucleus per cell, but it often features striations and is found only in the heart.
While both smooth muscle and cardiac muscle can have a single nucleus, the question specifically targets smooth muscle as it is composed of cells that are entirely uninucleated and function involuntarily throughout various organ systems.
