Accepted Answer

The superior oblique muscle inserts on the superior, lateral surface of the eyeball. The inferior oblique inserts on the inferior, lateral surface, the lateral rectus inserts on the lateral surface, and the superior rectus inserts on the superior surface of the eyeball.

Question 4

Which eye muscles are involved in focusing the eye for vision?&#10;A) extrinsic eye muscles&#10;B) intrinsic eye muscles&#10;C) extraocular eye muscles&#10;D) oculomotor muscles

Accepted Answer

The intrinsic eye muscles, specifically the ciliary muscle and the iris sphincter muscle, are responsible for focusing the eye for clear vision. The extrinsic eye muscles and extraocular eye muscles are responsible for moving the eye within the socket. The oculomotor muscles include several muscles, some of which are extrinsic eye muscles and some of which are intrinsic eye muscles. Therefore, B is the best choice as it specifically mentions the muscles involved in focusing the eye for vision.

Question 5

Your little brother just stuck his tongue out at you. Which tongue muscle did he use?&#10;A) hyoglossus&#10;B) stylohyoid&#10;C) genioglossus&#10;D) orbicularis oris

The genioglossus muscle controls the protrusion and retraction of the tongue, making it the muscle used when sticking out the tongue. The hyoglossus muscle helps to depress the tongue, the stylohyoid muscle elevates the hyoid bone, and the orbicularis oris is responsible for puckering and closing the lips.

The frontal belly of epicranius muscle is responsible for raising the eyebrows and producing horizontal wrinkles in the forehead. The medial pterygoid muscle is located in the jaw and is responsible for closing the jaw. The temporalis muscle is responsible for closing the jaw and moving the jaw side to side. The zygomaticus major muscle is responsible for lifting the corners of the mouth in smiling.

The lateral pterygoid muscle is responsible for opening the jaw and protruding the mandible. The medial pterygoid, temporalis, and masseter muscles are also involved in chewing and moving the jaw but do not have the same specific actions as the lateral pterygoid.

Question 9

All of the following are muscles that create movements of the tongue EXCEPT ________.&#10;A) levator veli palatine&#10;B) palatoglossus&#10;C) hyoglossus&#10;D) genioglossus

Question 10

All of the following control eye movements EXCEPT ________.&#10;A) superior rectus&#10;B) inferior rectus&#10;C) medial rectus&#10;D) orbicularis oris
