Joints



Individual bones of the skull are joined by sutures.
A suture is an example of a fibrous joint



Joints are formed when bones come in close proximity to each others and they are mainly of three types; fibrous, cartilagenous and synovial.



Fibruos joints are formed when a fibrous tissue unite between bones.

 

All the joints in the midline of the body are secondary cartilagenous joints

 

The synovial joints are the most complex among the three and they allow the widest range of movement

On the other hand cartilagenous joints are of two types, primary and secondary. What differentiate them into these two main sub- categories?

can you recall examples for these?

Mnemonis

Mnemonics is a technique to improve memory. Anatomy makes use of mnemonics and it is fun.

The most common one is the one used to memorize the names and sequence od the Carpal bones; "She Looks Too Pretty, Try To Catch Her". The first letter of each word in the sentence refers to a carpal bone (ie, Scaphoid, Lunate,Triquitral, Pisiform, Trapezium, Trapezoid, Capitate, Hamate)

Another one for the muscles that flex the elbow

Three B's Bend the elBow:
Brachialis
Biceps
Brachioradialis

The one that I like is the one that describes the attachment of muscles at the intertubecular groove of humerus
"A Lady between two majors"Teres major attaches to medial lip of groove.
Pectoralis major to lateral lip of groove.
Latissimus (Lady) is on floor of groove, between the 2 majors.
