THE SUSPECTS
WHAT ARE THE THREE TYPES OF FIBROUS JOINTS?
SYNDESMOSES, GOMPHOSES AND SUTURES
WHERE IN THE BODY WOULD YOU FIND A SUTURE JOINT?
THE SKULL
DETECTIVES, WHAT TYPE OF CONNECTIVE TISSUE HOLDS THE BONES TOGETHER IN A FIBROUS JOINT?
DENSE FIBROUS CONNECTIVE TISSUE
A DETECTIVE WAS INVESTIGATING A BODY. HE OBSERVED THE CONNECTION BETWEEN A TOOTH AND THE BONE OF ITS SOCKET. WHAT MAKES THIS CONNECTION DIFFERENT FROM A SUTURE?
CLUE: PROVIDE THE STRUCTURAL DIFFERENCES
GOMPHOSIS CONNECTS A TOOTH TO ITS SOCKET WHILE A SUTURE CONNECTS TWO BONES USUALLY OF THE SKULL
WHICH TYPE OF FIBROUS JOINT CONNECTS BONES WITH A LIGAMENT OR INTEROSSEOUS MEMBRANE?
SYNDESMOSES
TWO BONES CONNECTED BY INTEROSSEOUS MEMBRANE IN THE FOREARM
RADIUS AND ULNA
MAIN FUNCTION OF FIBROUS JOINTS
STABILTY/SUPPORT/HOLDING BONES TOGETHER/ LITTLE TO NO MOVEMENT
A JUNIOR DETECTIVE IS ASKED TO NAME A FIBROUS JOINT THAT CAN PERMIT SLIGHT MOVEMENT. SHE STATED SYNOVIAL JOINT. SHOULD WE SLAP HER OR FIRE HER IMMEDIATELY?
neither! just throw a fire hydrant at her! how did she even pass the entrance exam???
CASE CLUE: I ANCHOR THE TOOTH WITHIN ITS SOCKET!
THE NAME OF THE SUSPECT IS.....
GOMPHOSES!
A JOINT IS FOUND BETWEEN A TOOTH AND THE ALVEOLAR SOCKET. A DETECTIVE CLAIMS ITS A SYNDESMOSE. IS HE RIGHT?
NO! HE IS A BIG FOOL AND SHOULD BE FIRED! LOCK HIM UP INSTEAD!
A FIBROUS JOINT HAS NO JOINT CAVITY. DOES THIS MEAN THE BONES ARE COMPLETELY UNABLE TO MOVE?
NO. SOME FIBROUS JOINTS, ESPECIALLY SYNDESMOSES, PERMIT SLIGHT MOVEMENT
A SENIOR DETECTIVE SAYSM "BECAUSE FIBROUS JOINTS CONTAIN CONNECTIVE TISSUE THEY MUST ALLOW THE SAME DEGREE OF MOVEMENT?" WHAT IS WRONG WITH THIS STATEMENT
ONE, HOW IS HE A SENIOR DETECTIVE? IDIOT.
LEMME BE PROFESSIONAL. [SIGH] THE DEGREE OF MOVEMENT VARIES AMONG THE THREE TYPES.
SUTURES AND GOMPHOSES--IMMOVABLE,
AND SYNDESMOSES-- SLIGHTLY MOVABLE
SUTURES
SOMEONE HAS AN INJURY INVOLVING THE CONNECTIVE TISSUE BETWEEN TWO BONES THAT NORMALLY ALLOW MINIMAL MOVEMENT. WHICH TYPE OF JOINT WAS MOST LIKELY AFFECTED?
SYNDESMOSES!
THREE CHARACTERISTICS OF A FIBROUS JOINT
BONES JOIN TOGETHER STRONGLY, PROVIDES STABILITY, LITTLE TO NO MOVEMENT
THREE SUSPECTS ARE FOUND AT THE SCENE: ONE INVOLVES A SKIULL BONE, ONE INVOLVES A TOOTH AND SOCKET BONE, AND ONE INVOLVES CONNECTED BY A MEMBRANE. WHAT ARE THE THREE SUSPECT IN ORDER?
SUTURE--GOMPHOSES--SYNDESMOSES
