Theme 1 Anatomy quiz Flashcards
which pair of spinal nerves arises from the intevertebral fo
T3
which 2 roots join spinal nerve T3 to the spinal cord
dorsal and ventral
in which root do afferent axons pass
dorsal
in which root do efferent axons pass
ventral
at which vertebral level do sympathetic preganglionic axons leave the spinal cord
T1-L3
thoracolumbar outflow
is the dorsal root ganglion sensory or motor
contains cell bodies of sensory axons in the peripheral ns
why are there no synapses in the dorsal root ganglion
synapses are only found in the motor ganglion of the autonomic nervous system
where do central branches of axons of neuronal cell bodies in dorsal root ganglion terminate
in spinal cord
which muscle attaches to the mastoid process
scm
which nerve emerges from the stylomastoid fo
facial CNVII
which 2 bones form the margin of the jugular fo
occipital and temporal
name the 4 structures that emerge from the jugular fo
CN 9, 10, 11
int jug vein
in which bone is the fo. ovale located
sphenoid
name the nerve that emerges from the fo. ovale
V3
what type of joint is formed at the coronal suture and what movement is possible at this joint
the joint is a suture
in adults these are immovable
what 2 bones are joined at the sagittal suture
left and right parietal
what 2 bones form the margin of the pterygomaxillary fissure
maxilla and lateral pterygoid of the sphenoid bone
which nerve lies deep to pterygomaxillary fissure
maxillary division of the trigeminal V2
which structure is transmitted by the foramen spinosum
middle meningeal artery
name the joint at which the mandibular fossa comprises one of the articular surfaces
TMJ
what type of joint is formed at the the TMJ
synovial
what are the anatomical features of a synovial joint
presence of capsule
synovial membrane
synovial fluid
joined surface lined with cartilage
which nerves have a ganglion that performs the same function as the dorsal root ganglion
facial and trigeminal
which nerves contain axons (or fibres) that synapse in an autonomic ganglion
oculomotor III facial VII (only ps synapse inside ganglion)
which nerves contain axons that synapse at neuromuscular junctions
oculomotor & facial (extraocular muscles)
trigeminal n (m. of mastication)
accessory n (scm)
hypoglossal (tongue muscles)
which nerves are capable of signalling pain
trigeminal and facial
