Human Nervous System Quiz

Human Nervous System

• The autonomic nervous system is responsible for involuntary actions like breathing and digestion.
• The brainstem is responsible for controlling heart rate and breathing.
• Dopamine is a neurotransmitter associated with feelings of pleasure and reward.
• The outermost layer of the brain is called the cerebrum.
• The spinal cord is responsible for transmitting sensory information to the brain, controlling voluntary movements, and controlling reflexes.
• The thalamus is responsible for processing and integrating sensory information.
• The sympathetic nervous system is responsible for the fight or flight response.
• Damage to the olfactory nerve (I) can cause loss of sense of smell.
• The hypothalamus is responsible for regulating body temperature and hunger.
• The myelin sheath in neurons speeds up the transmission of nerve impulses.

Human Excretory System

• The functional unit of the kidney is called a nephron.
• Filtration is the process of removing waste products from the blood.
• The urinary bladder is responsible for storing urine before it is eliminated from the body.
• Antidiuretic hormone (ADH) regulates water reabsorption in the kidneys.
• The ureters transport urine from the kidneys to the bladder.
• The glomerulus is the structure of the nephron responsible for filtration.
• The kidneys excrete waste products such as urea, creatinine, and uric acid.
• Reabsorption is the process by which water and useful substances are reabsorbed back into the blood from the kidney tubules.
• The urethra serves as a passage for urine from the bladder to the outside of the body.
• The kidney is responsible for producing urine.

Additional Facts

• The cerebellum is responsible for coordinating voluntary muscle movements and maintaining balance and posture.
• A synapse is the gap between two neurons where communication occurs.
• The peripheral nervous system consists of the spinal cord and nerves throughout the body.
• The occipital lobe is primarily responsible for processing visual information.
• The somatic nervous system is responsible for controlling voluntary movements of skeletal muscles.
