Questions to get ready for the MBlex state board
Question | Answer |
---|---|
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, and temporal. |
Frontal Lobe (Cerebrum) | associated with reasoning, planning, parts of speech, movement, emotions, and problem solving |
Parietal Lobe (Cerebrum) | associated with movement, orientation, recognition, perception of stimuli |
Occipital Lobe (Cerebrum) | associated with visual processing |
Temporal Lobe (Cerebrum) | associated with perception and recognition of auditory stimuli, memory, and speech |
Cerebellum | "little brain", is similar to the cerebrum in that it has two hemispheres and has a highly folded surface or cortex. This structure is associated with regulation and coordination of movement, posture, and balance. |
Pons Varolii | part of the metencephalon in the hindbrain It is involved in motor control and sensory analysis, information from the ear first enters the brain in the pons. It has parts that are important for the level of consciousness and for sleep. also movement |
Medulla Oblongata | this structure is the caudal-most part of the brain stem, between the pons and spinal cord. It is responsible for maintaining vital body functions, such as breathing and heartrate |
Synarthrotic Joints | Allow extremely limited or no movement at all. Examples: cranial sutures, teeth in sockets |
Amphiarthrotic Joints | Are slightly moveable Examples: Intervertebral discs, tibiofibular joints |
Diarthrotic joints | Are freely movable joints. Examples: shoulder, knee |
Synovial Joints | Articulating bones separated by a joint cavity, enclosed in a joint capsule and lubricated by fluid |
Fibrous joints | Bones are held together by collagenous fibers extending from bone to bone with no joint cavity |
Cartilaginous Joints | Bones held together by cartilage with no joint cavity |
Carpals (8 per hand) | Scaphoid, Lunate, Triquetrum, Pisiform, Trapezium, Trapezoid, Capitate, Hamate |
Tarsals (6 and cal) | medial cuneiform, intermediate cuneiform, lateral cuneiform, navicular, cuboid, talus, and calcaneus. |
Tactile corpuscle/Meissner's corpuscles | They are a type of nerve ending in the skin that is responsible for sensitivity to light touch. These corpuscles are particularly sensitive to touch and vibrations |
Bulboid corpuscle/Krause end bulbs | The End bulb of Krause is a thermoreceptor that picks up on the sensation of cold temperatures. |
Bulbous corpuscle/Ruffini end organs | class of slowly adapting mechanoreceptor thought to exist only in the glabrous dermis and subcutaneous tissue of humans. It is named after Angelo Ruffini. |
Lamellar corpuscle/Pacinian corpuscles | They are nerve endings in the skin, responsible for sensitivity to vibration and pressure. Vibrational role may be used to detect surface, e.g., rough vs. smooth. |
Haversian canal | ___ typically run parallel to the surface and along the long axis of the bone. The canals and the surrounding lamellae are called a __ or an osteon. |
Volkmann's canals | also known as perforating holes, are microscopic structures found in compact bone. They run within the osteons perpendicular to the Haversian canals, |
Peritoneal cavity | potential space between the parietal peritoneum and visceral peritoneum, the two membranes that separate the organs in the abdominal cavity from the abdominal wall. being the pleural cavities around the lungs and the pericardial cavity around the heart. |
Medullary cavity | he central cavity of bone shafts where red bone marrow and/or yellow bone marrow is stored; hence, the medullary cavity is also known as the marrow cavity. Located in the main shaft of a long bone, the medullary cavity has walls composed of spongy bone |
