Articulations - Human Anatomy and Physiology I

A comprehensive set of vocabulary flashcards covering key concepts from the Human Anatomy and Physiology I lecture on articulations.

Articulations

Joints where two bones meet, allowing for movement and support.

Synarthrosis

A type of joint with no movement between articulating bones.

Amphiarthrosis

A type of joint allowing a small amount of movement between articulating bones.

Diarthrosis

Freely moveable joints allowing a wide variety of specific movements.

Fibrous Joints

Joints fastened by dense regular collagenous connective tissue, lacking joint space.

Cartilaginous Joints

Joints connected by cartilage, lacking a joint cavity and allowing little motion.

Sutures

Immovable joints between the edges of bones, making up the cranium.

Gomphosis

An immovable joint between each tooth and its bony socket in the jaw.

Syndesmosis

A type of joint where two bones are joined by a ligament or membrane, allowing slight movement.

Synovial Joints

Freely moving joints characterized by a synovial fluid-filled cavity.

Articular Cartilage

A thin layer of hyaline cartilage covering exposed articulating bones.

Synovial Fluid

Thick liquid in synovial joints, providing lubrication, transport of nutrients, and shock absorption.

Bursa

A synovial fluid-filled fibrous structure that minimizes friction in joints.

Tendon Sheath

A long bursa that surrounds tendons, protecting them as they move across joints.

Nonaxial Joints

Joints that allow motion in one or more planes without movement around an axis.

Biaxial Joints

Joints that allow motion around two axes.

Multiaxial Joints

Joints that allow motion around three axes.

Angular Movements

Movements that increase or decrease the angle between articulating bones at a joint.

Gliding Movements

Sliding motions between articulating surfaces of nonaxial joints.

Rotation

Nonangular motion where one bone rotates around an imaginary line along its axis.
