Presentation Transcript
Slide 1:The Systems, Structures, and Cells That Make Up Your Nervous System Chapter 3
The Anatomy of the
Nervous System
Neuroanatomical Techniques :Neuroanatomical Techniques Golgi stain – allows for visualization of individual neurons
Nissl stain – selectively stains cell bodies
Electron microscopy – provides information about the details of neuronal structure
Neuroanatomical Tracing Techniques :Neuroanatomical Tracing Techniques Anterograde (forward)
tracing where axons project away from an area
Retrograde (backward)
tracing where axons are projecting into an area
Slide 4:Directions in the Vertebrate Nervous System
Slide 5:Directions in the Vertebrate Nervous System (continued)
Directions in the Vertebrate Nervous System (continued) :Directions in the Vertebrate Nervous System (continued) Anatomical directions ignore the fact that humans walk upright. Therefore, top of the head both “dorsal” (back) and “superior” (top)
Other directions:
Medial – toward the middle
Lateral – toward the side
Proximal – close
Distal – far
Sections of the Brain :Sections of the Brain Horizontal – a slice parallel to the ground
Frontal (coronal) – slicing bread or salami
Sagittal – a midsagittal section separates the left and right halves
