Stylohyoid muscle greater cornu, and just superior the omohyoid muscle. It thus belongs to the group of suprahyoid muscles. When contracted, it elevates the hyoid, this action is primarily brought about during swallowing. It is perforated, near its insertion, by the intermediate tendon of the digastric muscle. A branch from the extracranial path of the facial nerve (CN VII) innervates the Stylohyoid muscle. It may be absent or doubled, lie beneath the carotid artery, or be inserted into the omohyoid, or mylohyoid muscles. The stylohyoid muscle elevates and retracts hyoid bone.Initiates a swallowing action by pulling the hyoid bone in a posterior
Cremaster muscle Cremaster muscle The cremaster muscle is a muscle that covers the testis and the spermatic cord. In human males, the cremaster muscle is a thin layer of striated and smooth muscle found in the inguinal canal and scrotum between the external and internal layers of spermatic fascia, surrounding the testis and spermatic cord. The cremaster muscle is a paired structure, there being one on each side of the body. Anatomically, the lateral cremaster muscle originates from the internal oblique muscle, just superior to the inguinal canal, and the middle of the inguinal ligament. The medial cremaster muscle, which sometimes is
