This category covers the three main types of joints in the human body—fibrous, cartilaginous, and synovial—explaining their structure, movement, and examples in the skeletal system.
Cartilaginous joints allow limited movement and are found between the vertebrae of the spinal column.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Joints - Fibrous Cartilaginous Synovial Types
Ball and socket joints, such as the hip and shoulder joints, allow movement in multiple planes.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Joints - Fibrous Cartilaginous Synovial Types
Fibrous joints, such as those found in the skull sutures, do not allow significant movement.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Joints - Fibrous Cartilaginous Synovial Types
The ball and socket joint allows movement in all directions, such as the shoulder and hip joints.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Joints - Fibrous Cartilaginous Synovial Types
Pivot joints, such as the atlantoaxial joint in the neck, allow rotational movement around a single axis.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Joints - Fibrous Cartilaginous Synovial Types
Synovial joints have cartilage on the articulating surfaces, which helps in smooth movement.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Joints - Fibrous Cartilaginous Synovial Types
Extension is the movement that increases the angle between two body parts, such as straightening the elbow.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Joints - Fibrous Cartilaginous Synovial Types
The knee joint between the femur and tibia is a hinge joint that allows movement in one direction.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Joints - Fibrous Cartilaginous Synovial Types
Fibrous joints, such as sutures in the skull, allow little to no movement.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Joints - Fibrous Cartilaginous Synovial Types
Hinge joints, such as the knee and elbow, allow movement in only one plane.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Joints - Fibrous Cartilaginous Synovial Types
The pivot joint between the atlas and axis vertebrae allows head rotation.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Joints - Fibrous Cartilaginous Synovial Types
The meniscus is a fibrocartilaginous structure that provides cushioning and shock absorption in synovial joints.
