Location, Location, Location I
What is the primary motor cortex.
I am the large gap between the left and right halves of the anterior spinal cord.
What is the Anterior Median Fissure?
I am called this before (anterior) the Optic Chiasm.
What is the Optic Nerve (CNII)?
The presence of unilateral tongue weakness means that this cranial nerve is involved
What is the Hypoglossal Nerve (CNXII)?
This section of the brain is in charge of motor planning.
What is the Pre-motor Cortex?
I drain the blood between the Cerebral Hemispheres
What is the Superior Sagittal Sinus?
The loss of temperature sensation indicates this tract is not functioning.
What is the Lateral Spinothalmic Tract?
I am a small part of the Right Frontal Lobe associated with speech.
What is the Broca's Area?
I am located deep to the Lateral Sulcus.
What is the Insular Cortex?
This nerve innervates the pupillary reflex
What is CN III (Oculomotor)?
This cranial nerve is injured if the eye is elevated and abducted rest.
What is CN IV (Trochlear)?
Testing symmetry of a smile indicates which nerve is intact?
What is Facial Nerve (CN VII)?
This artery is a branch off the Posterior Cerebral Artery and feeds the primary visual cortex.
What is the Calcarine Artery?
This tract mainly affects the arms, fine-tuning the coordination of reaching.
What is the Rubrospinal Tract?
This cistern (holds fluid) is located anterior to the Cerebellum.
What is the 4th Ventricle?
I am the white matter near the Basal Ganglia.
What is the Internal Capsule?
Which Cranial Nerve feeds the Lateral Rectus Muscle?
What is Abducens nerve.
Testing jaw motions is done to test which cranial nerve?
What is the Trigeminal Nerve (CN V)?
What structure is severed when there is bitemporal hemianopsia?
What is the Optic Chiasm?
This artery feeds the posterior cerebellum and lateral Pons and if injured will result in facial paralysis and sensory loss.
What is the Anterior Inferior Cerebellar Artery?
This inhibitory pathway causes the homonymous muscle to relax following a stretch.
What is the GTO pathway?
I sprout from the ANTERIOR portion of the Spinal Cord and become motor axons.
What are Anterior Roots/Rootlets?
I lie against the skull and spinal canal surrounding the central nervous system.
What is the Dura Mater?
This nuclei is where the optic tract splits to become the optic radiations.
What is the Lateral Geniculate Body/Nucleus.
Any lesion of the optic radiations results in this type of pattern of visual field loss.
What is a quadrantanopia?
This lobe is responsible for understanding what we hear.
What is the Parietal Lobe?
If this artery is injured, a person will have greater LE weakness than UE weakness.
What is the Anterior Cerebral Artery?
This tract runs only to the cervical spinal cord and mainly affects head and neck automatic movements.
What is the Medial Vestibulospinal Tract?
This system exists through the brainstem and is associated with arousal and alertness
What is the Reticular Activating System
I am located in both the skin and joints and react to movement (stretch and position).
What are Ruffini Endings?
The eye is positioned down and toward the temporal side of the face when this nerve is damaged.
What is CN III (Occulomotor)?
This nerve makes us produce tears and salivate.
What is CN VII (Facial N)?
A person will present with ptosis, dilated pupil and paralyzed eye movements if this artery is injured.
What is the Posterior Communicating Artery?
This descending tract runs the entire length of the spinal cord, decussates where it exits the cord, and ensures we remain standing by inhibiting flexors.
What is the Medial Reticulospinal Tract?
