Nervous System
The end of the spinal cord at L1/L2 vertebral level
What is the Conus Medullaris?
Feeling a mosquito bite on your arm
This large superficial back muscle helps shrug the shoulders.
What is the trapezius?
Actions of the Latissimus Dorsi and it's innervation.
What is, extension from a flexed position, adduction, and medial rotation of the shoulder & Thoracodorsal nerve?
Damage to the Facial Nerve, which causes paralysis to sturctures innervated by the nerve.
What is Bell's Palsy?
What is, somatic innervates the skin, skeletal muscle, and bone & Visceral innervates involuntary organs?
Upper and lower motor neurons activating the diaphragm and intercostal skeletal muscles during voluntary deep breathing or speaking
What is GSE (General Somatic Efferent)?
This cranial nerve primarily innervates the trapezius muscle.
What is the accessory nerve (CN XI)?
Muscle/s that retract the scapula.
What is, the trapezius, rhomboid major & minor?
What is, V1:ophthalmic, V2:maxillary, & V3:mandibular?
What is, there are more neurons/cells originating and going to this area, so they take up more space.
Sweat glands activating when you are hot
What is, GVE (General Visceral Efferent)?
The middle fibers of the trapezius primarily perform this action on the scapula.
What is scapular retraction?
Muscle/s that elevate the scapula.
What is, the trapezius & levator scapulae?
Actions and innervation of the Sternocleidomastoid muscle.
What is, lateral flexion and flexion of the head and neck. Innervated by the accessory nerve?
CNS cell bodies live here, whereas PNS cell bodies are found here.
What is, gray matter and ganglia?
Chemoreceptors in blood vessels detecting low oxygen or high carbon dioxide levels and sending signals to the brainstem to adjust breathing rate
What is GVA (General Visceral Afferent)?
Action performed by the superior and inferior parts of the trapezius muscle.
What is, superior rotation of the scapula?
Muscle/s that inferior rotate the scapula.
What is, the levator scapulae, rhomboid major, rhomboid minor, and latissimus dorsi?
Unilateral & bilateral actions of the Splenius muscle.
What is, unilateral: laterally flexes neck, bilaterally: extends head & neck?
In the CNS, axons travel in this. Whereas, in the PNS, axons form this.
What is, the white matter & the nerves?
Baroreceptors in the carotid sinus detecting changes in blood pressure and sending signals to the brainstem for cardiovascular regulation
What is GVA (General Visceral Afferent)?
Three attachments of the trapezius.
What is, external occipital tuberance, nuchal ligament, and spinous processes of thoracic vertebrae?
Only muscle that acts on the glenohumeral joint because it attaches to the humerus.
What is, latissimus dorsi?
The 4 Suprahyoid muscles & the 4 Infrahyoid muscles.
What is, digastric, mylohyoid, geniohyoid, stylohyoid (SUPRAhyoid) & sternohyoid, sternothyroid, thyrohyoid, omohyoid (INFRAhyoid)?
