Types of Movement
Amoeboid, ciliary, and muscular movements are exhibited by cells within the human body, contributing to crucial physiological functions and locomotion【4:1†source】.
Muscle
Muscles are essential for movement and locomotion, categorized into skeletal, visceral, and cardiac muscles based on location, appearance, and control regulation. Special properties include excitability, contractility, extensibility, and elasticity【4:1†source】.
Skeletal System
The skeletal system provides the structural framework for the body, enabling support and movement facilitated by bones and cartilages. It is divided into axial and appendicular skeletons【4:2†source】.
Joints
Joints are pivotal in facilitating movement by linking bones or cartilages. Types of joints include fibrous, cartilaginous, and synovial, each supporting different degrees of movement【4:4†source】.
Disorders of the Muscular and Skeletal System
This section discusses various disorders such as arthritis, osteoporosis, and muscular dystrophy, affecting the muscles or bones and impacting mobility and physical activities【4:4†source】.
What are the three main types of muscles found in the human body and where are each located?
Describe the sliding filament theory of muscle contraction.
Explain how a muscle contraction is initiated in the human body.
How are skeletal, cartilaginous, and synovial joints different from each other?
What roles do actin and myosin play in muscle contraction, and how are they structured?
