|
|
what part of the midbrain is the tegmentum and what does it control
|
front (basal) and controls motor functions
|
|
|
what part of the midbrain is the tectum and what does it control
|
alar and controls sensory functions

|
|
what does the myelencephalon contain and where is it located
|
the medulla; caudal portion of the hindbrain
|
|
|
what part of the hindbrain runs through both the medullar and pons
|
sulcus limitans
|
|
|
where are the 2 primary flexures

midbrain and cervical (where hindrain meets spinal cord)
|
|
|
what is the secondary flexure
|
pontine
|
|
|
where is the pontine flexure located
|
