43
What is the innervation of the scalp?
in the anterior part of the scalp the nerve supply is by all three branches of the trigeminal nerve
in the posterior half of the scalp nerve supply is from cutaneous branches of cervical spinal nerves C2 and C3
44

brachial plexus
upper limbs

What are valveless veins called that run form the outside to inside of the skull bones?
emissary veins
61
What is diploe?
spongy cancellous bone separating the inner and outer layers of cortical bone of the skull
62
What potentil grave complication could arise form scalp infections due to the presence of emissary veins?
can spread infection intracranially

Are there lymph node sin the scalp?
no
lymph drains away from scalp into lymph nodes of the head and neck
