The striatum (pl.: striata) or corpus striatum [5] is a cluster of interconnected nuclei that make up the largest structure of the subcortical basal ganglia. [6] The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia.
The case study also gives all students taking the AP Computer Science exams with a common experience from which to draw additional test questions. On each of the exams, at least one free-response question was derived from the case study. There were also five multiple-choice questions that are derived from the case study.
Lung parenchyma showing damage due to large subpleural bullae. Parenchyma (/ p ə ˈ r ɛ ŋ k ɪ m ə /) [1] [2] is the bulk of functional substance in an animal organ or structure such as a tumour. In zoology, it is the tissue that fills the interior of flatworms. In botany, it is some layers in the cross-section of the leaf. [3]

The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
The salience network is theorised to mediate switching between the default mode network and frontoparietal network (central executive network). [1] [2] [3]The frontoparietal network (FPN), generally also known as the central executive network (CEN) or, more specifically, the lateral frontoparietal network (L-FPN) (see Nomenclature), is a large-scale brain network primarily composed of the ...
Epidural space is the smallest at the cervical region, measuring 1 to 2 mm. At L2 to L3, enlarges until 5 to 6 mm. It then enlarges progressively until lower lumbar and sacral region. [7] However, some authors stated that it decreases in size after mid-lumbar region until 2 mm at S1 level. [8]
The AP exam uses paper and pencil. (With the exception of year 2020, only Create and Explore were tested. In 2021, only Create and the multiple choice section were tested.) [7] It lasts 180 minutes and includes approximately 76 questions. The exam is composed of two sections: 74 Multiple-Choice Questions
