These five cost-effectiveness tests are the participant cost test (PCT), the. utility/program administrator cost test (PACT), the ratepayer impact measure test (RIM), the. total resource cost test (TRC), and the societal cost test (SCT).
The brain is composed of 3 main structural divisions: the cerebrum, the brainstem, and the cerebellum (see the images below). At the base of the brain is the brainstem, which extends from the upper cervical spinal cord to the diencephalon of the cerebrum.ross Anatomy: Meninges. The meninges consist of 3 tissue layers that cover the brain and spinal cord: the pia, arachnoid, and the dura mater (see the image below). The pia along with the arachnoid are referred to as the leptomeninges, whereas the dura is referred to as the pachymeninx.
Outside the brain. This is an outside view of the brain. The brain is split into the left and right hemispheres by the longitudinal fissure. The different brain areas are segmented by deep grooves, called sucli , and by functional aspects. The largest part of the human brain is the cerebral cortex (cortex means bark in latan). This is an appropriate name, because the brain does its computation only on the six surface layers. The very back part of the brain contains the cerebellum (little brain), which is attached to the Hindbrain.
