Parts and Functions of the Brain and Nervous Systems
Question | Answer |
---|---|
Which brain part is a hindbrain structure involved in body movement, balance, coordination, fine-tuning motor skills, and cognitive activities such as learning and language? | Cerebellum |
Which brain part is the thin outer layer of the cerebrum, in which much of human thought, planning, perception, and consciousness takes place? | Cerebral Cortex |
Which brain part is each of the large halves of the brain that are covered with convolutions, or folds? | Cerebrum |
Which brain part is nerve fibers that connect the two hemispheres of the brain? | Corpus Callosum |
Which of the three brains controls cognitive, sensory and motor function and regulates temperature, reproductive functions, eating, sleeping and the display of emotions? | Forebrain |
Which lobe helps with organization, planning and creative and abstract thinking? | Frontal Lobe |
Which of the three brains is involved in the most basic processes of life and contains the medulla, pons and cerebellum? | Hindbrain |
Which brain part is a limbic structure; the master regulator of almost all major drives and motives we have, such as hunger, thirst, temperature, and sexual behavior; also controls the pituitary gland. | Hypothalamus |
Which brain part regulates emotions and motivations? | Limbic System |
Which brain part is a hindbrain structure that extends directly from the spinal cord; regulates breathing, heart rate, and blood pressure. | Medulla |
Which of the three brains processes auditory and visual information, controls eye muscles and initiates voluntary movement of the body? | Midbrain |
Which lobe processes visual signals? | Occipital Lobe |
Which lobe of the brain plays an important role in sensation and perception? | Parietal Lobe |
Which brain part is a hindbrain structure that serves as a bridge between lower brain regions and higher midbrain and forebrain activity? | Pons |
Which brain part controls fine movement and sends information to control body movement? | Primary Motor Cortex |
Which brain part is a forebrain structure that receives information from the senses and relays it to the cerebral cortex for processing? | Thalamus |
Which lobe of the brain's main function is hearing and are also involved in emotion and memory? | Temporal Lobe |
Which brain part is the frontmost portion of the parietal lobe and receives information from touch sensors? | Somatosensory Cortex |
Which part of the nervous system is made up of all the nerves of the peripheral nervous system that serve involuntary systems of the body, such as the internal organs and glands? | Autonomic Nervous System |
Which part of the nervous system comprises the brain and spinal cord? | Central Nervous System |
Which part of the nervous system comprises all the nerve cells in the body outside the central nervous system? | Peripheral Nervous System |
Which part of the peripheral nervous system is made up of nerve cells that transmit sensory information to the central nervous system (CNS) and those that transmit information from the CNS to the skeletal muscles? | Somatic Nervous System |
Which branch of the autonomic nervous system activates bodily systems in times of emergency? | Sympathetic Nervous System |
Which branch of the autonomic nervous system relaxes or returns the body to a less active, restful state. | Parasympathetic Nervous System |
