2.Decide which statements are TRUE or FALSE, give reasons for false ones.  

1 Gray matter has projections which are called horns.  F

Gray matter has outgrowths they are called horns.

2. Ventral roots and horns transmit the nerve impulse from the muscles to the brain.  F

   The abdominal (anterior) roots and horns transmit nerve impulses (commands) from the brain to the muscles, causing them to contract and make certain movements

3. There are 35 segments in the spinal cord.  F

   There are 31 segments in the spinal cord

4. The dorsal roots and horns transmit information from sensitive cells, receptor cells, to the brain. T

5. Grey matter consists of bundles of neurons bodies and dendrites. F

   Gray matter (substantia grisea) is one of the components of the human central nervous system, which consists of cell bodies (neuronal bodies), neuropils (clusters of unmyelinated axons, dendrites, glial cell offshoots), synapses, glial cells (astrocytes and oligodendrocytes), and capillaries.

6. In the brain there are also three membranes. T

7. The spinal cord performs three functions. F
