Questions and Answers

Match the following brain division with its structures:

Cerebrum = Telencephalon, Diencephalon Brain Stem = Mesencephalon, Myelencephalon, Metecephalon Cerebellum = Metecephalon, Spinal Chord Spinal Chord = Spinal Chord

Match the following Telencephalon structures with their functions:

Neocortex = Thinking, reasoning, problem solving Hippocampus = Involved in retrieval & storage of info Basal ganglia = Controls conscious & voluntarily movements of skeletal muscles Limbic System (Olfactory Bulb) = Perceives & processes sensory information from environment

Match the following Diencephalon structures with their functions:

Thalamus = Perceives & processes sensory information from environment Hypothalamus = Controls conscious & voluntarily movements of skeletal muscles Pineal body = Involved in retrieval & storage of info Third ventricle = Regulation of sleep and wake cycle

Match the following Metencephalon and Mesencephalon structures with their functions:

<p>Reticular Formation = Regulation of sleep and wake cycle Corpa Qualigemina = Perceives &amp; processes sensory information from environment Cerebellum = Controls conscious &amp; voluntarily movements of skeletal muscles Pons = Involved in retrieval &amp; storage of info</p> Signup and view all the answers

Match the brain structure with its function:

<p>Diencephalon (thalamus) = Acts as relay center for sensory information on its way to cerebral cortex Hypothalamus = Regulates body temperature, hunger, thirst, and release of hormones Brainstem = Controls breathing, heartbeat, and blood pressure, serves as pathway for ascending and descending nerve tracts, and coordinates reflex actions Cerebellum = Controls precise voluntary muscle movements coordination and integrates input from inner ears and muscles</p> Signup and view all the answers

Match the embryonic brain structure with its derivatives:

<p>Prosencephalon = Turns into Telencephalon and Diencephalon Mesencephalon = Forms part of the midbrain Rhombencephalon = Turns into Metencephalon and Myelencephalon Neural tube = Creates presynaptic autonomic neurons of PNS, motor neurons of Peripheral Nervous System, and neurons of Central Nervous System</p> Signup and view all the answers

Match the germ layer derivatives with their structures:

<p>Ectoderm = Creates nervous system, cornea and lens of the eye, and tooth enamel Mesoderm = Forms skeletal system, muscular system, circulatory &amp; lymphatic system, and dermis of skin Endoderm = Produces epithelial lining of digestive tract, lining of respiratory system, liver, and pancreas Neural crest = Creates sensory neurons in Peripheral Nervous System, postsynaptic autonomic neurons, and adrenal medulla</p> Signup and view all the answers

Match the location with the type of neuron cell bodies:

<p>Peripheral Neurons = Cell bodies outside CNS that can be located along spinal cord or near tissue/organs Central Neurons = Located within CNS to process information Presynaptic Autonomic Neurons of PNS = Derived from neural tube and involved in transmitting signals from organ to CNS to muscles/glands Sensory neurons in Peripheral Nervous System = Derived from neural crest and involved in transmitting sensory information</p> Signup and view all the answers

Match the stage of embryonic brain development with its characteristics:

<p>Stage 1 (5 weeks) = Prosencephalon turns into Telencephalon and Diencephalon; Mesencephalon forms part of the midbrain; Rhombencephalon turns into Metencephalon and Myelencephalon Fertilized egg attachment = Forms hypoblast on the inside and epiblast on the outside; separates the developing embryo into sections with mesoderm in the middle Neural tube formation = Creates U-shaped groove which completes enclosing process to form the hollow neural tube; increases in volume as mesoderm thickens Yolk sac closure = Starts to pinch and close on itself at middle of embryo</p> Signup and view all the answers

Match the function with the neural structure it creates:

<p>Presynaptic Autonomic Neurons of PNS = Transmits signals from organ to CNS to muscles/glands Motor Neurons of Peripheral Nervous System = Involved in controlling voluntary muscle movements Neurons of Central Nervous System = Process information within CNS Postsynaptic Autonomic Neurons = Involved in receiving signals from presynaptic autonomic neurons</p> Signup and view all the answers

What are the main functions of the thalamus and hypothalamus in the diencephalon?

<p>Thalamus acts as a relay center for sensory information on its way to the cerebral cortex, while the hypothalamus regulates body temperature, hunger, thirst, and the release of hormones.</p> Signup and view all the answers

Explain the role of the brainstem in the nervous system.

<p>The brainstem controls breathing, heartbeat, and blood pressure, serves as a pathway for ascending and descending nerve tracts, and coordinates reflex actions.</p> Signup and view all the answers

What are the primary functions of the cerebellum?

<p>The cerebellum controls precise voluntary muscle movements and coordination, as well as integrating input from the inner ears and muscles.</p> Signup and view all the answers

Explain the role of the spinal cord in reflex actions.

<p>The spinal cord coordinates reflex actions without involving the brain, acting as a highway for signals leaving and going into the brain.</p> Signup and view all the answers

Describe the embryonic origins of the brain and spinal cord.

<p>The brain originates from three primary structures: prosencephalon, mesencephalon, and rhombencephalon. The spinal cord begins as the neural tube created from the ectoderm.</p> Signup and view all the answers

Differentiate between peripheral neurons and central neurons based on their locations.

<p>Peripheral neurons have cell bodies outside the central nervous system and can be located along the spinal cord or near tissues/organs, while central neurons are located within the central nervous system and process information.</p> Signup and view all the answers
