ARTICULATION TROCHOIDEA Meaning and
Definition
-
Articulation trochoidea refers to a type of joint found in the body, also known as a pivot joint. It is a synovial joint that allows rotary movement or rotation around a single axis. The word "articulation" refers to the joining or connection between two bones, while "trochoidea" comes from the Greek word "trochos," meaning "wheel," indicating the rotational nature of this joint.
In an articulation trochoidea, one bone has a rounded, cylindrical surface that fits into a corresponding ring-shaped structure or depression in another bone. This type of joint allows the bones to articulate and spin or pivot around a central axis, but only in one plane of movement. The axis of rotation for a pivot joint is primarily located at the center of the rounded bone, which allows for the rotational movement without any significant other motion.
A classic example of an articulation trochoidea joint is the connection between the atlas (the first cervical vertebra) and the axis (the second cervical vertebra). The rounded structure of the axis (dens) rotates within the ring-shaped structure (anterior arch) of the atlas, enabling the "no" movement of the head.
Overall, articulation trochoidea describes a joint in which rotation occurs around a single axis, facilitating specific movements within the body, such as turning the head or twisting the forearm.

Etymology of ARTICULATION TROCHOIDEA
The term "articulation trochoidea" is derived from two components: "articulation" and "trochoidea".
The word "articulation" comes from the Latin word "articulatio", which means "joint" or "a jointed connection". is associated with the verb "articulare", meaning "to divide into joints" or "to join together with joints". The term "articulation" is used to refer to the action or process of connecting joints or the state of being jointed.
The term "trochoidea" is derived from the Greek word "trokhoeides", which combines "trokhos" meaning "wheel" and "eidos" meaning "shape" or "form". describes something that is wheel-shaped or circular in form.
When combined, "articulation trochoidea" refers to a specific type of joint that resembles or functions like a wheel or pulley.
