depressor labii inferioris muscle
1.17 - 4
depressor anguli oris muscle
origin vs insertion of muscle
The origin is the attachment site that doesn’t move during contraction, while the insertion is the attachment site that does move when the muscle contracts. The insertion is usually distal, or further away, while the origin is proximal, or closer to the body, relative to the insertion.
what is the action of the occipitofrontalis muscle
the frontal belly of the occipitfrontalis muscle elevates the eyebrows and wrinkles the forehead, as when a person looks surprised
innervation of occipitofrontalis muscle
terminal branches of the facial nerve; temporal branch
epicranial aponeurosis
The epicranial aponeurosis (aponeurosis epicranialis, galea aponeurotica) is an aponeurosis (a tough layer of dense fibrous tissue) which covers the upper part of the cranium in humans and various other animals.
innervation of all the muscles of facial expression
facial nerve CN VII
bells palsy
Bell’s palsy is the result of a malfunction of the facial nerve (cranial nerve VII), which controls the muscles of the face. Facial palsy is typified by inability to move the muscles of facial expression. The paralysis is of the infranuclear/lower motor neuron type.
