1- Formed by the junction of greater petroal n + deep petrosal n.
2- Enters the pterygopalatine fossa posteriorly after passing the pterygoid canal and joins the pterygopalatine ganglion on the posterior aspect.
3-it contains:
A- Special sensory afferent fibers (Taste)
B- Preganglionic parasympthatic fibers.
C- Postganglionic sympthatic fibers.
Hope that helps!
(From Wikipedia)The internal carotid artery passes superiorly from the carotid canal in the base of the skull, emerging via that part of the foramen lacerum which is not occluded by cartilage.The artery of pterygoid canal, the nerve of pterygoid canal and some venous drainage also pass through the foramen lacerum.The nerve of pterygoid canal comprises the deep petrosal nerve and the greater petrosal nerve the former carrying sympathetic fibres and the latter parasympathetic fibres of the autonomic nervous system to blood vessels, mucous membranes, salivary glands, and lacrimal glands.Furthermore, one of the terminal branches of the ascending pharyngeal artery (itself a branch of the external carotid artery) passes through the foramen lacerum. The ascending pharyngeal artery is one of three possible "meningeal branches" of this vessel.Lastly, some emissary veins pass through the foramen lacerum. These connect the extracranial pterygoid plexus with the intracranial cavernous sinus and present an unopposed route for infection.
Medial pterygoid
Central (Haversian) Canal is the canal that runs through the core of each osteon.
Masseter, temporalis, lateral, pterygoid medial, pterygoid are the chewing muscles which move your teeth so you can bite the carrot stick
Optic nerve and ophthalmic artery passes through this foramen to your eye ball.

the Chorda Tympani nerve ( a branch of the facial nerve VII) which joins the lingual nerve medial to the lateral pterygoid muscle.
Medial pterygoid
Masseter Temporalis Medial pterygoid Lateral pterygoid
The medial pterygoid muscle, the left medial pterygoid will deviate the jaw to the right and vice versa.
The lateral pterygoid muscle allows us to chew.
in males the contents of the inguinal canal are: spermatic cord, illioinguinal nerve, genital branch of genitofemoral nerve. in females: the round ligament of uterus and illioinguinal nerve.
the lateral pterygoid
Most nerve entrapment syndromes are caused by injury to the nerve as it travels between a canal consisting of bone or ligament.

Masseter, temporalis, medial pterygoid and lateral pterygoid are the four muscles are utilized to chew food.
