Muscles are specialized tissues that can undergo contraction and relaxation and provide movements of body parts or whole body. The study of muscles is called myology. They also function to hold body parts in postural positions, movement of body fluids and heat production.
Definition
Muscles: The specialized tissues that can undergo contraction and relaxation and provide movements of body parts or whole body are called muscles.
Myology: The study of muscles is called myology.
Main Idea
Muscles are specialized tissues.
They can undergo contraction and relaxation.
They provide movements of body parts or whole body.
They also function to:
Hold body parts in postural positions
Move body fluids
Produce heat
The study of muscles is called myology.
There are three types of muscle tissues:
Core Concept
Muscles = specialized tissues for movement
Myology = study of muscles
Functions = movement, posture, movement of body fluids, heat production
Types = smooth, cardiac, skeletal
Smooth muscles = spindle-shaped; single nucleus; involuntary; in hollow organs
Cardiac muscles = branched; single nucleus; intercalated discs; in heart
Skeletal muscles = striated; multinucleate; voluntary; attached to bones
