Peripheral Nervous system Flashcards
(16 cards)
Running from spinal cord to spinal nerve describe the structures of both the dorsal and ventral structures
Dorsal
-Spinal cord, Dorsal rootlets, dorsal roots, dorsal root ganglion, spinal nerve
Ventral
-Spinal cord, ventral rootlets, ventral roots, spinal nerve
-,
what does the spinal cord travel through, what are the immediate branches coming off the spinal nerve which one is larger?
Intervertebral foramen
-ventral nerve, larger
-dorsal nerve, smaller
Phrenic nerve
what is its origin and what is its role
originates from c3,4 and 5
innervates the diaphragm, important for respiration
what nerve is this
Femoral nerve
what nerve is this
obturator nerve
What nerve is this
Sciatic nerve
nerve at “Q”, what does it innervate?
Optic nerve-eye
Nerve at “E” what does it innervate
Trigeminal nerve (only nerve that originates from the pons)-muscles of massteraction
Nerve at “G”, what does it innervate?
Facial nerve- muscles of facial expression
Nerve at “L”, what does it innervate?
Vestibulo-cochlear nerve- organs of balance and hearing within the ear
Nerve at “H”, what does it innervate?
Vagus nerve -internal organs in thorax and abdomen.
Nerve at “A”, what does it innervate?
Olfactory nerve, (note the swollen structure is the olfactory bulb, within is the where the olfactory nerve sits)-nose
in regards to BIOM2020 content, what are the two nerves which stem from the posterior division of the brachial plexus?
Axillary nerve and Radial nerve
in regards to BIOM2020 content, what is the nerve that derives from the lateral division of the brachial plexus?
Musculocutaneous nerve
in regards to BIOM2020 content, what are the nerves which derive from the media division of the brachial plexus?
Median nerve and Ulnar nerve
From lateral to medial, what is the order of the bracial nerves required by BIOM2020
Axillary, musculocutaneous, radial, median, ulnar
