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 Cerebrum: The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebral cortex is divided into four sections, called lobes: the frontal lobe, parietal lobe, occipital lobe, and temporal lobe.he brain is made of three main parts: the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus (part of the limbic system). The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons and medulla.
