Term
| Define microscopic anatomy and reference two types. |
|
Definition
| Microscopic anatomy is the study of structures visible under the microscope. It includes Cytology (cellular anatomy) and histology (tissue anatomy) |
|
|
Term
| Define the three ways to divide a brain and explain each. |
|
Definition
| A brain can be divided via a sagittal section which splits the brain into the left and right halves; a transverse section which removes the face from the back of the head; and a horizontal section which cuts off the top of the head. |
|
|
Term
| Describe the anatomical position and state its significance. |
|
Definition
| The anatomical position is standing, hands at sides, palms forward and feet forward. It is significant because all anatomical terms use the anatomical position as a reference point. |
|
|
Term
|
Definition
| The neuraxis is an imaginary line through the spinal cord to the front of the brain. The neuraxis bends in humans. |
|
|
Term
| True or False: The belly button is located superior the knee, inferior the neck, and ipsilateral the nose. |

|
Term
| Define the 3 major divisions of the and how they reflect the portions of the developmental brain. |
|
Definition
| The 3 major divisions of the brain are the forebrain, the midbrain and the hindbrain. They reflect the rostral, middle and caudal portions of the developmental brain. |
|
|
Term
| True or False: The membranes surrounding the brain are called the cranial meninges. |
|
Definition
|
|
Term
| Name the membranes surrounding the brain. |
|
Definition
| The outer most layer is the dura mater, the middle layer is the aracunoid mater and the deep layer is called the pia mater. |
|
|
Term
| Differentiatethe dura layers. |
|
Definition
| The outer dura contains blood vessels and nourishes the bones of the skull, whereas the inner dura extends down into the longitudinal fissure and also reaches into the transverse cerebral fissure. |
|
|
Term
| True or False: The large blood vessels serving the brain lie in the dura mater. |
|
Definition
| False. The large blood vessels serving the brain lie in the subaracnoid space. |
|
|
Term
| Define the function of the pia mater. |
|
Definition
| The pia mater is the inner most layer which directly covers and dips down into the folds of the brain. Most blood to the brain is supplied by the large number of vessels in the pia mater. |
|
|
Term
| True of False: The arachnoid mater is a delicate tissue bound to the pia mater by capillaries. |
|
Definition
| False. The arachnoid mater is a delicate tissue bound to the pia mater by protein threads. |
|
|
Term
| Define Cerebral Spinal Fluid. |
|
Definition
| Cerebral Spinal Fluid (CSF) is a clear liquid, similar to blood plasma, that provides an environment in which the brain "floats". It acts as a cushion to the brain. |
|
|
Term
| Where is cerebral spinal fluid manufactured. |
|
Definition
| The ventricles of the brain manufacture cerebral spinal fluid. |
