Summary
Acupoints are anatomical structures composed of neurovascular bundles and connective tissue, acting as crucial sites for qi and blood circulation. These points are classified into cleft, tunnel, and terminal types based on their distinct anatomical features.
Area of Science:
- Anatomy
- Acupuncture Research
- Physiology
Context:
- Traditional Chinese Medicine (TCM) posits acupoints as key elements in regulating bodily functions.
- Understanding the anatomical basis of acupoints is crucial for refining acupuncture techniques and efficacy.
- Previous research has focused on the functional aspects, necessitating a deeper anatomical investigation.
Purpose:
- To elucidate the anatomical characteristics of acupoints.
- To classify acupoints based on their structural and anatomical features.
- To explore the relationship between acupoint anatomy and qi and blood circulation.
Summary:
- Acupoints are identified as anatomical formations comprising a 'kernel' (neurovascular bundles) and a 'shell' (clefts or tunnels formed by musculoskeletal structures).
- The 'shell' regulates the 'kernel's' function, influencing qi and blood flow.
- Acupoints are anatomically classified into three types: cleft, tunnel, and terminal, each with distinct structural compositions and locations within the body's meridian system.
Impact:
- Provides a detailed anatomical classification of acupoints, enhancing understanding of their structural basis.
- Offers insights into the mechanism of qi and blood regulation through acupoint structures.
- Facilitates a more precise application of acupuncture by correlating anatomical features with therapeutic functions.

Functional Classification of Joints
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Structural Classification of Joints
Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.

Anatomical Terminology
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...
Classification of Bones
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.

Bone Markings
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

Joints
Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
