Anterior neck Flashcards
what is the function of the sternocleidomastoid
helps you bend your neck and turn and tilt your head.
what borders the submandibular triangle
anterior and posterior digastric and the mandible
what does the submandibular triangle house
the supramandibular salivary gland, submandibular lymph nodes, facial artery/vein, mylohyoid muscle and hypoglossal nerve
what borders the submental triangle
the mandible, anterior belly of digastric muscle, hyoid bone and mylohyoid muscle
what does the submental triangle house
submental lymph nodes and anterior jugular vein
what borders the carotid triangle
posterior belly of digastric muscle, superior belly of omohyoid muscle and the SCM
what does the carotid triangle house
interior jugular vein, carotid artery & vagus nerve, all within carotid sheath, deep cervical lymph nodes, hypoglossal nerve, ansa cervicalis
what borders the muscular triangle
omohyoid, sternohyoid and SCM
what does the muscular triangle house
thyroid and parathyroid gland
what does the sternocleidomastoid connect to
manubrium of sternum to occiput
and clavicle to mastoid process
what is the platysma
superficial muscle arising from the fascia covering the upper parts of pectoralis major and deltoid
what is the function of the platysma
facilitates facial expression - pulldown of mandible and opening of lower lip
what is the trapezius
superficial muscle extending from the cervical to thoracic region of posterior neck
what is the function of the rectus capitus anterior
pull occipital down for neck flexion
what is the rectus capitis anterior attached to
Arises from anterior surface of the lateral mass of atlas (C1) and the roots of its transverse process.
Ascends to the inferior surface of the basilar parts of the occipital bone
what innervates the rectus capitis anterior
C1/C2 ventral rami
what is the ventral rami
carries sensory and motor fibers for the innervation of the muscles, joints, and skin of the lateral and ventral body walls and the extremities
what is the function rectus capitis lateralis
contraction allows lateral flexion to same side
what innevates the rectus capitis lateralis
C1/C2 ventral rami
what is the rectus capitis lateralis attached to
Arises from upper surface of transverse process of atlas inferior surface of jugular process of occipital bone.
what is the function of the longus colli
flexes neck foward and laterally and the obliques allow rotation to opposite side
what are the three sections of the longus capitis
superior and inferior obliques and vertical intermediate
what innervates the longus colli
C2-C6 ventral rami
what is the longus colli attached to
anterior surface of vertebral column between C1 and T3
what are the four vertebral muscles of the anterior neck
rectus capitis anetrior, rectus capitis lateralis, longus colli and longus capitis
what innervates the longus capitis
C1-C3 ventral rami
what is the function of the longus capitis
flexes the head
what is the longus capitis attched to
arises from anterior tubercles of transverse processes of C3/4/5/6 and ascends into the inferior basilar part of occipital bone
what innervates the anterior scalene
C4/5/6 central rami
what is the anterior scalene attached to
runs from transverse process of C3-C6 to rib 1
