Flashcards in Random Deck (19):
What is attached to the greater tubercle of the humerus?
What is attached to the crest of the greater tubercle of the humerus?
What is attached to the lesser tubercle of the humerus?
What is attached to the crest of the lesser tubercle of the humerus?
What is attached to the intertubercular groove?
Where are the cell bodies of the parasympathetic nervous system located?
The intermedidiolateral grey horn of spinal segments T1-L2
Which rami communicans are more plentiful? What do they do?
Gray because there's one for every ganglion of the sympathetic trunk and they are output fibers
Where are the cell bodies located in the parasympathetic NS?
In the nuclei of the brainstem (cranial nerves) and in spinal cord segments S2-4.
How do the preganglionic parasympathetic fibers travel out from the brainstem and spinal cord levels?
Via the cranial nerves (3,7,9,10) and pelvic splanchnic nn
What fibers to cranial nerves contain? What doe they never contain?
Motor, sensory, parasympathetic
Name the ganglia associated with the cranial nerves
Splanchnic nn extend from the ________ ganglia to the _________ ganglia.
Prevertebral ganglia (celiac, sup/inf mesenteric)
Which vertebra levels exhibit typical spinal nerves?
What are the exceptions to the general rules of muscles/innervations in the superficial flexor compartment of the forearm?
All mm. innervated by median nerve, EXCEPT flexor carpi ulnaris is innervated by the ulnar nerve.
What are the exceptions to the general rules of muscles/innervations in the deep flexor compartment of forearm?
Flexor digitorum profundus is innervated by BOTH the ulnar and median nn.
What are the exceptions to the general rules of muscles/innervations in the hand?
All intrisics (interossei and lumbricals) are innervated by the ulnar nerve EXCEPT the lateral 1 & 2 lumbricals which are innervated by the median n.
Lumbricals attach from the __________ tendons to the ________ side of the dorsal digital expansion.
Flexor digitorum profundus
Palmar lumbricals attach to which digits and have how many heads
