What is an anteflexion?

Anteflexion is a term used in anatomy to refer to the forward bending or tilting of a body part. It specifically describes the forward bending of a joint, occurring in the sagittal plane. The sagittal plane divides the body into left and right halves.

Anteflexion is most commonly used in the context of the human body. Examples include:

1. Anteflexion of the neck: This is the tilting of the head forward at the joint between the skull and the first cervical vertebra (C1). It brings the chin closer to the chest.

2. Anteflexion of the arm: This refers to the forward bending of the arm at the elbow joint, bringing the forearm toward the upper arm.

3. Anteflexion of the hip: This is the forward bending of the hip joint, bringing the thigh closer to the abdomen.

4. Anteflexion of the knee: This involves the forward bending of the knee joint, decreasing the angle between the thigh and lower leg.

5. Anteflexion of the spine: This is a curvature of the spine with the concavity facing anteriorly. It is the condition where the lumbar vertebrae are bent forward, causing the lower back to curve inward.

6. Anteflexion of the pelvis: This is the tilting of the pelvis forward, which can be caused by certain muscle imbalances or conditions such as anteverted uterus.

7. Anteflexion of the uterus: In gynecology, anteflexion of the uterus refers to the forward bending of the uterus from its normal position.

Anteflexion can occur naturally as part of normal movement, or it can be a result of certain medical conditions, such as weak or imbalanced muscles, joint contractures, or neurological disorders. It can also be part of certain yoga poses or physical therapy exercises aimed at improving flexibility or strength.

It's important to distinguish anteflexion from hyperextension, which refers to the backward bending or tilting of a body part.
