Pia mater Flashcards
Innermost meningeal layer
Pia mater characteristics
Microscopically thin, delicate and highly vascular membrane
the pia mater adheres to the
surface of the brain, closely following its contours
The pia mater is separated from the brain by the
subpial space
formed by the end-feet of the astrocytes (glia limitans)
Many _____________________ of the brain are related to the pia mater, some are _________________, while others are suspended by the ________________
superficial blood vessels
partially embedded within its thickness
arachnoid trabeculae
Pia mater functions
Physically separate the neural tissue from the blood vessels in the subarachnoid space, adding to the efficacy of the blood-brain barrier
Contributes to the degradation of the neurotransmitters, preventing their prolonged action on the nervous tissue
