Across
- 5. dorsal surface of the midbrain
- 6. black substance
- 10. It means toward the head
- 11. are a network of cavities that are distributed throughout the brain.
- 12. comes from the Greek word for “Membrane” and refers to 3 membranes that surround the brain and spinal cord.
- 14. it is located at the upper back portion of the brain, is associated with somatosensory processing.
- 18. it is a technique used to examine the intricate details of neuronal structure.
- 19. it is a circuit of midline structures that circle the thalamus
- 21. cells that forms the myelin sheath.
- 24. are the gaps between sections of myelin.
- 26. one of the important components of the sensorimotor system
- 28. a neuron with more than two processes extending from its cell body.
- 29. it receives inputs from the neocortex
- 30. It was utilized by Santiago Ramón y Cajal in the late 19th to early 20th centuries, was essential in his groundbreaking research on the nervous system.
Down
- 1. it provide nutrients to neurons, maintain their extracellular environment, and provide structural support.
- 2. House of many ascending and descending tracts and parts of the reticulum formation and the anterior part of the hindbrain.
- 3. branch like structures that receive messages from other neurons and allow the transmission of messages to the cell body.
- 4. cells which provide nutrients and structural support to neurons.
- 7. it is one-shaped region at the junction between the axon and the cell body.
- 8. are cells that are specialized for the reception, conduction, and transmission of electrochemical signals
- 9. It is the most posterior region of the brain stem. The myelencephalon accommodates most of the nucleus regions of the cranial nerves as it is the transition between the spinal cord and the brain.
- 13. help support, connect, and protect the neurons of the central and peripheral nervous systems.
- 15. this is used to map the paths of axons projecting away from cell bodies in a specific area.
- 16. This staining method, commonly employing cresyl violet dye, permeates all cells on a slide but selectively binds to molecules abundant in neuron cell bodies, such as DNA and RNA.
- 17. the ridges between fissures & sulci
- 20. Made up of seven vertebrae called the C1-C7. These bones allow a person to turn, lift, tilt, and nod their head.
- 22. it is located below the anterior thalamus
- 23. the metabolic center of the neuron; also called the soma, which contains nucleus and many organelles.
- 25. it is a midline nucleus located at the anterior tip of the cingulate cortex.
- 27. It is composed of cell bodies and unmyelinated interneurons.
