Explain the main function/responsibility of the nervous system:, Your nervous system's main function is to send messages from various parts of your body to your brain., Explain the difference between the cerebrum, cerebellum, and brainstem:, Cerebrum: is the largest part of the brain and responsible for controlling speech, memory, emotions, intelligence, reasoning, thinking and sensation. Cerebellum: known as the little brain and responsible for balance, posture and muscle coordination. Brain stem: base of the brain and connects the brain to the spinal cord; controls the basic life functions: heartbeat, breathing and digestion., Explain the difference between the left and right hemisphere?, The left brain controls the right side of the body and the right brain continues the left side of the body. Left side: Controls language, speech, reading, writing, and calculations. Right brain:Controls art, music, face recognition, and visual imagery. Controls art, music, face recognition, and visual imagery., Explain the difference between the four lobes: Frontal, parietal, temporal, and occipital., Frontal: action and thought, Parietal: sensation and touch, Temporal: hearing and memory, Occipital: vision, Explain the difference between voluntary and involuntary body functions and give an example of each., Voluntary actions: actions you consciously choose to do and control with your brain; example: kicking a soccer ball. Involuntary functions: actions that happen automatically without your conscious thought or control.actions that happen automatically without your conscious thought or control.:, Explain what nerve cells are AND describe the difference between motor and sensory nervous., Nerve cells, also called neurons, are special cells in your body that act like a communication system.They receive information, process it, and then send messages to other parts of the body. Sensory nerves send messages to your brain (help you feel). Motor nerves send messages from your brain (help you move).Motor nerves send messages from your brain (help you move)., Describe the role of the spinal cord., The spinal cord is like a message pathway between your brain and your body., Alzheimers, Alzheimer’s affects brain function, memory, and physical mobility, Cerebral Palsy, Cerebral palsy is a condition that affects how a person moves and controls their muscles., Brain Tumour, A brain tumour is a growth of extra cells in the brain. It can make it harder for the brain to do its job., Epilepsy, Epilepsy is a condition that affects the brain (sends mixed up messages) and can cause seizures., Headaches, A headache is pain in your head or forehead., Head Injuries, A head injury happens when your head gets hurt, like from a fall or a hit., Explain how you can support your nervous system health., Regular exercise, 7-9 hours of sleep, a balanced diet, What is a reflex arc? When is it important to have a good reaction time? What can affect your reaction time?, A reflex arc is a super-fast nerve pathway that lets your body react automatically to danger. It is important to avoid danger,( stopping your bike), for sports (hitting a baseball) or to respond quickly to a question. Being tired, age, practice, and distractions can affect your reflex arc., Explain the main function of the musculoskeletal system:, The main job is to provide structure, protection, and movement, allowing them to walk, run, play, and grow., Explain the role bones play in the human body AND what bones are made of:, Our bones give our bodies shape, and support and protect our organs and systems. Bones are made of living tissue. They contain a hard mineral called calcium phosphate for strength and a protein called collagen for flexibility. They also have blood vessels and bone cells that help them grow and repair themselves., Explain the difference between joints, cartilage, ligaments and tendons:, Joints are the place where movement happens. Cartilage is the cushion in that place. Ligaments are the straps holding it together. Tendons are the cables making it move., Explain the difference between smooth, cardiac, and skeletal muscles:, Smooth muscle is in organs and moves things inside your body (like food and air). Cardiac muscle is in the heart and pumps blood. Skeletal muscle helps you move your body and keep good posture., Arthritis, Arthritis is a condition that causes pain and swelling in the joints (like knees, hands, or hips)., Osteoporosis, Osteoporosis is a condition where your bones become weak and brittle so they can break easily.., Fracture, A fracture is when a bone breaks., Strains and Sprains, A strain is when a muscle or tendon is stretched or torn (like overusing a muscle). A sprain is when a ligament is stretched or torn (ligaments connect bones at joints)., Tendonitis, Tendonitis is when a tendon becomes swollen and sore from overuse or injury., Explain how you can support your musculoskeletal health:, Move your body daily, eat for strength, protect your body, good posture and get enough sleep.
