Branches of the Subclavian Artery 3D

  • Vertebral Artery

    • * Arises from the first part of the subclavian artery.
    • * Ascends through the cervical vertebrae, passing through the transverse foramina.
    • * Provides blood to the cervical vertebrae and contributes to the blood supply of the brain, especially in the posterior circulation.

 

  • Internal Thoracic (Mammary) Artery

    • * Arises from the first part of the subclavian artery.
    • * Descends anteriorly along the chest wall.
    • * Supplies the chest wall and the breast.

 

  • Thyrocervical Trunk

    • * Arises from the first part of the subclavian artery.
    • * Divides into several branches, each with its specific path.
    • * Its branches include the inferior thyroid artery (thyroid gland), transverse cervical artery (neck muscles), and suprascapular artery (scapular region).

 

  • Branches of Thyrocervical Trunk

  • Inferior Thyroid Artery

    • * Arises from the thyrocervical trunk.
    • * Descends towards the thyroid gland, supplying it and giving off an ascending cervical branch.
    • * Provides blood to the thyroid gland and surrounding structures.

 

  • Transverse Cervical Artery

    • * Arises from the thyrocervical trunk.
    • * Runs transversely across the neck, passing posteriorly to the sternocleidomastoid muscle.

    • * Arises from the internal carotid artery.
    • * Supplies the choroid plexus, optic tract, and some parts of the brain, running deep within the brain.

 

  • Anterior Cerebral Artery

    • * Branches from the internal carotid artery.
    • * Extends anteriorly to supply the medial and superior parts of the cerebral hemispheres.

 

  • Middle Cerebral Artery

    • * Arises from the internal carotid artery.
    • * Passes laterally and supplies the lateral surfaces of the cerebral hemispheres

 

 

  • External Carotid Artery

    • * Arises from the common carotid artery.
    • * Gives off numerous branches within the neck.
    • * Its branches include the superior thyroid artery (thyroid gland), lingual artery (tongue), facial artery (face and submandibular region), occipital artery (scalp), posterior auricular artery (ear and scalp), maxillary artery (maxilla and associated structures), and superficial temporal artery (scalp and temporal region).

 

  • Branches of External Carotid Artery

  • Superior Thyroid Artery

    • * Arises from the external carotid artery.

    • * Provides blood to the thyroid gland and laryngeal structures.

 

  • Lingual Artery

    • * Arises from the external carotid artery.
    • * Ascends to supply the tongue, traveling deep within the oral cavity.
    • * Provides blood to the tongue and floor of the mouth.

 

  • Facial Artery

    • * Arises from the external carotid artery.
    • * Runs a tortuous course to supply the face, ascending to the corner of the mouth.
    • * Provides blood to the facial muscles and structures of the face.

 

  • Occipital Artery

    • * Arises from the external carotid artery.
    • * Ascends posteriorly, supplying the scalp and adjacent areas.
    • * Provides blood to the posterior scalp.

 

  • Posterior Auricular Artery
