MOVEMENT OF LOWER JAW – MAXILLARY INFERIOR
The only movable bone of the head is the jawbone (Inferior maxillary). The two knob-like heads fit into sockets in the temporal part of the skull just behind the entrances to the eardrums. The flat, pointed ends in front of the knobs slide under the Zygomatic arch. The large muscle called the masseter controls the mastication and grinding of food. The masseter is attached from under the Zygomatic arch to the end of the lower jaw.The temporal muscle raises and lowers the jaw. It comes from the temporal part of the skull to the top ridge of the Inferior maxillary.
Look at the images above. The muscles that control the mouth are called the Buccinators (cheek muscles) and the muscles of expression are called lesser and greater Zygomatics. They are connected from the Zygomatic arch down to the circular ring of cartilage surrounding the mouth.
DRAWING HUMAN FACIAL FEATURES – Nose, Eyes, Mouth, Ears, etc
The features are the parts of the face that give it expression. When they are immobile the face is blank and expressionless. The features normally express what the brain is thinking. It is important to know their structure in order to best express the emotions of the figure. A great deal of time is spent by students of the drama learning how to transmit to the audience the character of the role they are playing. Many times the features convey quickly what would take a great many words to explain.
Facial expression plays an important part in the fine and commercial arts. Michelangelo said a great deal with the expressions on the faces of both his sculpture and painting.
The sale of products in commercial art depends a great deal upon the expression of people handling, using or eating them in advertisements. Man uses his features as a method of communication every day of his life. A nose is not just a blob put on a face, a mouth not just an opening and eyes not just two dots, each feature has a basic structure. Learning their shape and muscular
construction will aid a great deal in your ability to create better pictures.
Look at the images above. The shape of the eye is almost round. It rests in a cushioned socket of bony structure surrounding it.
Four main muscles, one on top and bottom and one on each side, govern its movement. The eye projects slightly out of its socket though both lids surround the eye. The only lid that moves is the upper one. Keep the eyes apart with the length of an eye
between them. On the following page is a simple explanation of the ear and mouth.
Look at the above pictures and imitate to learn how to draw human ears.
Look at the example Illustrations above of female and male mouths to learn how to draw a person’s mouth and lips on your own.
