Carpel, One of the leaflike, seed-bearing structures that constitute the innermost whorl of a flower. One or more carpels make up the pistil. Fertilization of an egg within a carpel by a pollen grain from another flower results in seed development within the carpel

Carpals:
Carpals are a group of bones located in the wrist of the human body. These bones play a crucial role in providing stability and flexibility to the wrist joint, allowing us to perform various movements and actions with our hands. The carpal bones are arranged in two rows, known as the proximal row and the distal row.

Structure:
The carpal bones are small and irregularly shaped. There are eight carpal bones in total, namely the scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, and hamate. These bones are connected to each other by ligaments, forming a strong and stable structure.

Function:
The carpals play a vital role in the movement and stability of the wrist joint. They allow for various movements, such as flexion, extension, abduction, adduction, and circumduction. These movements are essential for everyday activities like writing, typing, gripping objects, and performing intricate hand movements.

Joint Types:
Joints are the points where two or more bones meet. They provide mobility and flexibility to our body, allowing us to perform different movements. There are three main types of joints in the human body:

1. Fixed or immovable joints: These joints do not allow any movement and are found in the bones of the skull. They provide stability and protection to the brain.

2. Slightly movable joints: These joints allow limited movement and are found in the vertebrae of the spine. They provide flexibility and shock absorption.

3. Freely movable joints: Also known as synovial joints, these joints allow a wide range of movements. They are found in the major joints of the body, such as the knees, elbows, shoulders, and hips. Synovial joints are further classified into different types based on their structure and movement capabilities.

- Hinge joints: These joints allow movement in one direction, like a hinge. The elbow and knee joints are examples of hinge joints.

- Ball and socket joints: These joints allow movement in multiple directions. The hip and shoulder joints are examples of ball and socket joints.

- Pivot joints: These joints allow rotational movement. The joint between the first and second vertebrae of the neck is an example of a pivot joint.

- Gliding joints: These joints allow sliding and twisting movements. The carpal bones in the wrist joint are an example of gliding joints.

In conclusion, carpals are the group of bones in the wrist that provide stability and flexibility to the wrist joint. Joints, on the other hand, are points where two or more bones meet. They can be fixed, slightly movable, or freely movable, depending on their structure and movement capabilities.
