Answer 1

Q.Of the following surface areas of the body, the one associated with the greatest amount of ​neural tissue in the primary somatosensory cortex is the __________, while the area​associated with the least is the __________:

ans:(b.) the lips/the backs of the legs.

Q.The function of the corpus callosum and the anterior commissure is to __________:

ans.( a) allow communication between the right and left hemisphere

synapse allows the communication between CNS & PNS.

Hormones from the hypothalamus reach the pituitary through hypophyseal portal system.

Blood brain barrier protect the brain from internally generated toxins.

Q. The part of the brain that governs voluntary control of striated skeletal muscles is the ​__________:

ans (a) primary motor cortex.

The function of primary sensor cortex is recieving the basic senses from the body(touch)

  The function of secondary occipital cortex is visual processing

The function of auxiliary ventral pathway is audio processing
