Head Flashcards
(16 cards)
What are the bones of the head?
Parietal Frontal Sphenoid Nasal Lacrimal Maxilla Mandible Zygomatic Temporal Occipital
What is the pterion?
“H-shaped” junction between frontal, parietal, sphenoid and temporal
What are the cranial nerves/what nerves do they involve?
Olfactory (sensory) Optic (sensory) Oculomotor (motor) Trochlear (motor) Trigeminal (both) Abducens (motor) Facial (both) Vestibulocochlear (sensory) Glossopharyngeal (both) Vagus (both) Spinal Accessory (motor) Hypoglossal (motor)
What is the function of the olfactory nerve?
Sense of smell
What is the function of the optic nerve?
Sense of vision
What is the function of the oculomotor nerve?
Innervates muscles around the eye
What is the function of the trochlear nerve?
Controls small muscle in eye
What is the function of the trigeminal nerve?
Sensory of face/muscle
What is the function of the abducens nerve?
Innervates extra ocular eye muscles
What is the function of the facial nerve?
Muscle of facial expression and sense of taste
What is the function of the vestibulocochlear nerve?
Hearing/balance
What is the function of the glossopharyngeal nerve?
Taste, gag reflex, throat
What is the function of the vagus nerve?
Autonomic regulation: heart rate, ventilation, digestion
What is the function of the spinal accessory nerve?
Motor control of sternocleidomastoid and trapezius
What is the function of the hypoglossal nerve?
Below tongue
What type of joints exists between the parietal and frontal bones? Discuss the joint.
Suture joints (temporomandibular is synovial)
-This joint has a disc inside: makes superior/inferior
compartment.
-Allows depression and elevation of the jaw, you can protrude and retract your jaw, and move it side to side.
-Has sensation from the trigeminal nerve
-trigeminal (CN V) nerve also controls muscles of chewing such as masseter and temporalis
