Parallel

the length of the fascicles run parallel to the long axis of the muscle.

Pennate

fascicles are attached obliquely to a central tendon.

Unipennate, bipennate, multipennate

What are the three (3) types of pennate arrangement?

Frontalis

muscle that covers the frontal bone, allow you to raise the eyebrows and to wrinkle the forehead.

Occipitalis

muscle that covers the posterior aspect of the bone, it pulls the scalp posteriorly.

Ocularis oculi

run in circles around the eyes.

Ocularis oris

circular muscle of the lips, also known as “kissing muscle”.

Buccinator

flattens the cheek. During chewing, it compresses the cheek to hold the food between the teeth.

Zygomaticus

“smiling muscle” because it raises the corners of the mouth upward.

Masseter

covers the angle of the lower jaw

Temporalis

acts as a synergist of the masseter in closing the jaw.

Platysma

pull the corners of the mouth inferiorly, producing a downward sag of the mouth.

Sternocleidomastoid

when both of these muscles contract together, it flexes the neck.
