Central Nervous System: brain and spinal cord fully solved 2023 passed

Central Nervous System: brain and spinal cord fully solved 2023 passedStructures that support and protect CNS - correct answer Cranial meninges and cerebrospinal fluid Function of cerebrospinal fluid - correct answer Cushioning delicate neural structures, supporting the brain and transporting nutrients, chemical messengers and waste products. White matter - correct answer Contains large numbers of of myelinated and unmyelinated axons. Carries information from place to place. Gray matter - correct answer Brain and spinal cord tissue that appears gray with the naked eye; consists mainly of neuronal cell bodies (nuclei) and lacks myelinated axons. Region of integration and command initiation. Cerebrum - correct answer Conscious thought processes, intellectual functions. Memory storage and processing. Conscious/subconscious regulation of skeletal muscle contractions. Diencephalon - correct answer Thalamus: processing centres for sensory information. Hypothalamus: controls emotions, autonomic functions and hormone production. Mesencephalon - correct answer Processing of visual and auditory data. Generation of reflexive somatic motor responses. Maintenance of consciousness. Pons - correct answer Relays sensory information to cerebellum and thalamus. Subconscious somatic and visceral motor centres. Medulla oblongata - correct answer Relays sensory information to thalamus and other portions of the brain stem. Autonomic centres for regulation of visceral function (CV, respiratory and digestive system activities)
