UAB Advanced Patho Objectives

Dorsal root column responsible for internal sensory information. (proprioception)joint and tendon sensation Special somatic afferent
Dorsal root column responsible for Innervating the skin and responding to stimuli such as those that produce pressure or pain General somatic afferent
Dorsal root column responsible for Innervating specializes gut-related receptors, such as taste buds and receptors of th olfactory. Special visceral afferent
Dorsal root column responsible for Innervating visceral structures such as gastrointestinal tract, urinary bladder, heart, and great vessels. General visceral afferent
What is the cerebellum and what does it do? Contribute to all movements, recieves proprioception, control of muscle movement. Ex. Signals stop movement precisely at intended point.
What is the thalamus and what does it do? Coordination and integration of peripheral sensory stimuli. Ex a person can recover from a coma and remember some of what was said at the bedside.
cranial nerve 1 and function olfactory - smell
cranial nerve 2 and function optic - reflexes central and peripheral sight
cranial nerve 3 and function oculomotor - pupil constriction, blink, accommodation, lid and eye movement
cranial nerve 4 and function trochlear - moving eyes ((down)) and in extrinsic eye movement
cranial nerve 5 and function trigeminal - muscles of mouth, chewing, face sensation
cranial nerve 6 and function abducens - lateral eye deviation (prevents double vision)
cranial nerve 7 and function facial- gag reflex, taste
cranial nerve 8 and function auditory - vestibulocochlear - hearing and head position - balance!
cranial nerve 9 and function glossopharyngeal - assists with swallowing, taste, gag reflex, sensation, salivary reflex
cranial nerve 10 and function vagus - visceral organs such as heart, lungs, bronchi, trachea, GI tract, external ear, parasympathetic effect, emesis, vocalization, and partakes in swallowing
cranial nerve 11 and function spinal accessory - sternocleidomastoid and trapezius muscles, shrug and test resistance
cranial nerve 12 and function hypoglosseal - tongue muscles - movements of tongue
What is the hypothalamus and what does it do? area of master-level integration of homeostatic control of the body's internal environment. ex. maintenance of blood gas concentrations, water balance, food consumption
What is the corpus callosum and what does it do? connects the cerebral cortex of the two sides of the brain
What is the basal ganglia and what does it do? supply axial and proximal unlearned and learned postures and movements (associated movements) ex arm swinging during walking and running
What is the CSF and what does it do?
What are the four lobes of the brain? frontal, parietal, occipital, temporal.
This spinal pathway is used for rapid transmission of sensory information such as precise touch regarding spacial orientation. discriminative pathway
This spinal pathway transmits sensory information such as pain, thermal sensations, crude touch, and pressure that does not require discrete localization of signal source or fine discriminatory of intensity. anterolateral pathway
This is the subdivision of the anterolateral pathway that has rapid transmission of sensory information to the thalamus neospinothalamic
This is the subdivision of the anterolateral pathway that has slow-conducting tracts that transmit sensory signals paleospinothalamic
Atrophy, fasciculations, and decreased reflexes and tone are seen with what type of motor neuron lesion? lower motor neuron lesion (LMN)
T or F. Weakness is seen in both UMN and LMN lesions. True. Weakness is seen in both lesions.
