Artikulasi (Persendian)

Introduction

This tutorial explores the concept of articulation, specifically focusing on human joints or persendian. Understanding the different types of joints is crucial for grasping how the human movement system operates. This guide will provide you with a step-by-step breakdown of the main types of joints, including diarthrosis, along with practical examples and visual aids from the referenced video.

Step 1: Understand the Basic Types of Joints

Familiarize yourself with the two primary classifications of joints in the human body:

• Sinarthrosis:

  • These are immovable joints.
  • Example: Sutures in the skull.

• Diarthrosis:

  • These are movable joints and are crucial for a wide range of motions.
  • Examples include hinge joints, ball-and-socket joints, pivot joints, and saddle joints.

Step 2: Explore Diarthrosis Joints

Dive deeper into diarthrosis joints, which allow for significant movement. Here are the main types:

1. Hinge Joints

   • Allow movement in one plane (flexion and extension).
   • Example: Elbow and knee joints.
   • Tip: Visualize the motion like a door swinging open and closed.

2. Ball-and-Socket Joints

   • Allow for rotational movement in multiple planes.
   • Example: Shoulder and hip joints.
   • Tip: Think of a ball in a cup, which can move freely in various directions.

3. Pivot Joints

   • Permit rotational movement around a single axis.
   • Example: The joint between the first and second cervical vertebrae (allows head rotation).
   • Tip: Imagine a rotating peg within a hole.

4. Saddle Joints

   • Allow for movement in two planes.
   • Example: The thumb joint.
   • Tip: Picture how a saddle fits on a horse, allowing movement forward, backward, and side to side.

Step 3: Visualize Joint Movements

To enhance your understanding, use visual aids from the video:

• Watch the segments demonstrating each type of joint in action.
• Pay attention to how joints work during various movements, which will help in memorizing their functions.

Step 4: Apply Knowledge Practically

Consider how these joints impact everyday activities:

• Hinge Joints: Used in actions like walking (knee movement) and lifting (elbow movement).
• Ball-and-Socket Joints: Essential for activities such as throwing (shoulder) and running (hip).
• Pivot Joints: Important for turning your head to look around.
• Saddle Joints: Crucial for gripping and grasping with your hands.

Conclusion

Understanding the types of joints and their functions is fundamental to grasping human movement. By familiarizing yourself with sinarthrosis and diarthrosis joints, along with their specific types and applications, you can better appreciate the complexity of the human skeletal system. As a next step, consider observing these joints in action during physical activities or sports to see how they facilitate movement.
