Muscles Of The Neck – 2

Muscles Of The Neck – 2


musculus sternocleidomastoid it start from
clavicle and attach to mastioid process temporal bone next group middle muscle muscles of the
neck divide in to muscle above of hyoid bone and muscles below of hyoid bone below of hyoid
bone are musculus sternohyoidus from sternum to hyoid bone sternothyridus go to thyriod
cartilage to hyoid bone and omohyoidus from scapula and go to hyoid bone musculus omo
hyoidus has two venters inferioir and sperioir and between intermediate tendon above of hyoid
bone digastric muscle musculus digastricus it also cosist of two venter anterioir and
posterioir than musculus stylohyoid from stylioid process to hyoid bone musculus mylohyiodus
do u remember sulcus mylohyoideus at the mandible in go hyoid bone musculus mylohyoideus above
of mylohyoideus from sina omentalis to hyoid bone pass musculus geniohyoideus and deep
muscles of the neck first of all three scalenus muscle musculus scalenus anterioir musculus
scalenus medial and musculus scalenus poterior anterioir middle muscle attach to first rib
if u remember on the first rib was tuberculum musculi scalini antrioris and behind of this
tuberculli groove of subclavin artry and behind of groove where attach middle scalens muscles
and posterioir muscles attach to second rib
next musculus logus colli musculus longus capitus musculus rectus capitus anterioir
and lateral next muscle of the head divide into muscles of mastication and muscle of
facial expression muscle of mastication sre musculus temporalis start from temporal fossa
and attack to coronary process of mandible musculus masseter start from zygomatic arch
and attach to ramus of mandible two pterygoid muscles musculus pterygoidus medialis and
musculus pterygoidus lateralis both of them start from pterygoid process and inferioir
surface of greater wings of synovial bone and attach to middle muscle attach tuberpterygoid
and lateral muscle attach neck of mandible to cartilage function all of this muscle move
mandible upward lateral pterigoid process if they contract together they move mandible
forward posterioir fiber of musculus temporalis move mandible backward and if musculus pterigoidus
only one side contract they move mandible on opposite side this muscles has fasia musculus
temporalis has fasia temporalis musculus masseter the same fasia fasia masseterica and in front
from meatus accousticus externus here it is parotid gland and parotid gland surround from
fasia peritide another muscle are muscle of facial expression and they have not got fasia
fasia are absent first muscle it is muscle of the roof of the skull musculus epicoronarus
it has venter frontralis and venter occipitalis and also in the region of auricle present
three auricle muscles musculus auricularis posterioir and musculus auricularis superioir
and musculus auricularis anterioir in the region of orbita present musculus orbicular
oculi and it has three parts part orbitalis attach to the wall of orbita pars palpabraris
on the eyelids and pars lacrimaris on the lacrimal sac next muscle it is musculus protrous
and next muscle is absent should be here musculus corogatur super cili muscles in the region
of mouth it musculus orbicularis oris musculus levator labi superioris it lift lips musculus
zygomaticus major and minor musculus levator anguli aurus it lift angle of the mouth and
musculus risorious muscle of the smile it start from the skin of the chin and attach
to the angle mouth musculus depresser anguli aurus and musculus depresser labi inferioiris
and musculus omentalis it is necessary to name of all these muscles next moment topography
of the neck neck has four region anterioir region infront musculus sternocleodmastiodu
all of this region it is anterioir region of
neck poterioir region it above of musculus tripizious between trapizious
and sternocleodomastiodus muscle this region it lateral region of the neck regiocervicalis
lateralis and last regiosternocleodomasteoidus it is projection of sternocledomasteoid muscles
two region anterioir and lateral divide into triangles here musculus omohyoidus this muscle
pass inthis two region in lateral and anterioir with the help of this muscle lateral region
divide into trigonum omoclaviculare trigonumomotripizidum and trigonumomotrachealie because here larynx
and trachea next triangle it is between musculus omohyoidus and musculus digastricus and musculus
sternocleodomasteoidus thriangle has name trigonumcaroticum because carotid artry pass
in this triangle and we can press it to anterioir tubecle of cerical 6 it is tubercle name is
tuberculum caroticum and next sub mandible
triangle trigonum retromandibulare it is between mandible and two venters of musculus digasteriu
and inside of this triangle smaller triangle pyrobos triangle in russian scientist name
.it has anterioir wall musculus mylohyoidus posterioir wall musculus digastricus and superioir
wall here it is absent should be nerve hypoglosus in this triangle lingual artry passs we can
tie this artry in time of bleeding that is topography of neck
