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.
The cerebellum (âlittle brainâ) is a structure that is located at the back of the brain, underlying the occipital and temporal lobes of the cerebral cortex (Figure 5.1). Although the cerebellum accounts for approximately 10% of the brainâs volume, it contains over 50% of the total number of neurons in the brain.
