This document provides information on classifying joints and facial expressions associated with medical conditions. It describes the mnemonic "SAD MEANS" to remember the three types of joints: synarthrosis (S) for immovable fibrous joints, amphiarthrosis (A) for slightly movable cartilaginous joints, and diarthrosis (D) for freely movable synovial joints filled with synovial fluid. It also lists facial expressions and their associations: snarling facies with myasthenia gravis, myotonic facies with myotonic dystrophy, torpid facies with myxedema, and mouse facies with chronic kidney failure.

1. 1. TRICK.... related to joint - SAD MEANS
S = FOR SYNARTHROSIS AND
A = FOR AMPHIARTHROSIS AND
D = FOR DAIARTHROSIS
CLASSIFICATION OF JOINTS.....
S - MEANS IMMOVABLE JOINT AND FIBROUS JOINT, FIXED
OINT B/W BONE AND CONNECTED BY FIBROUS TISSUE EXMPLE
SUTURES OF THE SKULL
A - MEANS SLIGHTLY MOVABLE AND CARTILAGINOUS JOINT
FILLING THE GAP B/W VERTEBRAE..
D - MEANS FREELY JOINT AND SYNOVIAL JOINT /FILLED WITH
SYNOVIAL FLUID
2. SNARLING FACIES – MYASTHENIA GRAVIS.
MYOTONIC FACIES – MYOTONIC DYSTROPHY.
TORPID FACIES – MYXOEDEMA.
MOUSE FACIES – CHRONIC KIDNEY FAILURE.
