MUSCULAR SYSTEM Flashcards
What is the basic action that all muscle functions are based on?
Contraction (shortening) of muscle fibers.
Which muscle function allows the body to move from one place to another?
Locomotion
What muscle function helps the body stay in a specific position, such as standing or sitting?
Maintain posture
Which muscle function is involved in regulating body temperature by producing warmth?
Heat production
Functions of Muscles:
• Locomotion
• Maintain posture
• Heat production
Types of Muscle Tissue:
- Skeletal muscle
- Smooth muscle
- Cardiac muscle
What type of muscle tissue is responsible for voluntary movements and is usually attached to bones?
Skeletal muscle
What characteristic distinguishes skeletal muscle in terms of appearance?
Striated muscle
Where is skeletal muscle commonly found in the body?
Usually attached to bones
What is the primary function of skeletal muscle?
Produce voluntary movements
What type of muscle tissue is found in the walls of organs like the digestive and urogenital systems, and most blood vessels?
Smooth muscle
What is the main characteristic of smooth muscle regarding its control and appearance?
Involuntary and unstriated muscle
Which nervous system regulates the contractility of smooth muscle?
Autonomic Nervous System (ANS)
What type of muscle tissue is restricted to the heart?
Cardiac muscle
How is cardiac muscle similar to skeletal muscle in terms of appearance?
It is considered striated muscle
What is the primary control mechanism for the contraction of cardiac muscle?
It contracts intrinsically and is not under voluntary control
