I've Got Your Back
The name of the vertebra that lacks a body and a spinous process, allowing it to articulate with the occipital condyles.
What is the atlas (C1)?
This landmark is the point where the sagittal and coronal sutures meet.
What is bregma?
The semispinalis muscles INSERT on these vertebral landmarks.
What are the spinous processes?
Dorsal roots carry this type of signal to the ipsilateral side of the body. (sensory or motor)
What is sensory?
The deep back muscles all rotate towards this side of the body. (contra or ipsi)
What is contralateral (opposite side)?
These ligaments tether the spinal cord to the arachnoid matter and run perpendicular to the cord.
What are the denticulate ligaments?
This foramen transmits the internal jugular vein and cranial nerves IX, X, and XI.
What is the jugular foramen?
The superior rectus muscle is innervated by this nerve.
What is the oculomotor nerve (CN III)?
The external carotid artery terminates by dividing into the maxillary artery and this other branch.
What is the superior temporal artery?
This branch of trigeminal nerve (CN V) is the only to possess dual composition (both sensory and motor).
What is the mandibular branch (CN V3)?
The common tendinous origin of the erector spinae muscles include the posterior iliac crest, SI ligaments, sacral and inferior lumbar spinous processes, and supraspinous ligament sacrum, and this.
What is the posterior sacrum?
Facial nerve (CN VII) exits the skull through the internal acoustic meatus and this other opening.
This suboccipital muscle is the ONLY in its group responsible for lateral bending of the head.
What is obliquus capitis superior?
This dual-composition cranial nerve provides sensory innervation to the carotid sinus and parotid gland.
What is the glossopharyngeal nerve (CN IX)?
Damage to this artery could cause significant impairment in brain function, since it supplies approximately 80% of the brain's blood flow.
What is the internal carotid artery?
This lumbar vertebral feature serves as an attachment point for the multifidus and intertransversarii muscles.
What is the mammillary process?
This landmark is considered the weakest point of the skull and the junction between the frontal, parietal, sphenoid, and temporal bones.
What is the pterion?
This anterior neck muscle is the only of its group to NOT be innervated by a branch of ansa cervicalis.
What is thyrohyoid?
Weakness in the geniohyoid and thyrohyoid muscles is likely due to damage to this nerve.
What is the hypoglossal nerve (CN XII)?
The sella turcica, located on the sphenoid bone, houses this depressed landmark where the pituitary gland sits.
What is the hypophyseal fossa?
A patient presents with excessive hyperextension of the spine following a traumatic injury, most likely due to damage to this spinal ligament.
What is the anterior longitudinal ligament?
The cribriform foramina, which provide passage for the olfactory nerve (CN I) are contained within this bone of the skull.
What is the ethmoid bone?
Difficulty producing unilateral movement of the mandible (grinding of the jaw) is likely due to damage to this muscle.
What is the medial pterygoid?
Compression of this vein, which runs deep to the sternocleidomastoid muscle and joins with the subclavian vein to form the brachiocephalic vein, can lead to impaired drainage of the brain and face.
What is the internal jugular vein?
What is the abducens nerve (CN VI)?
