Study Notes
Skeletal, Muscular & Nervous Systems
- Muscle strength is a measure of a muscle's ability to exert force.
- Antagonistic muscle pairs work together to produce movement. One muscle contracts (flexor) while the other relaxes (extensor). Examples include biceps and triceps (flexion/extension of the forearm).
- The skeletal system provides structural support and protection for the body. It also allows for movement.
- Bones are defined as hard, supportive tissues composing the skeleton. Bone performs many functions: support, protection, and blood cell production.
- Two additional functions of bone include calcium storage and fat storage.
- Bones can store fat (True).
- Joints are the points where two or more bones meet.
- Various types of joints are present in the body
- A neural pathway involving sensory nerves, motor nerves, and the spinal cord is involved in reflex actions (like catching a dropped ruler)
Circulatory & Respiratory Systems
- The heart's primary function is to pump blood throughout the body.
- Blocking oxygen delivery to the brain can result in brain damage or death.
- Necrosis is the death of tissue.
- Pulse or heart rate is the rhythmical throbbing of arteries felt due to the contractions of the heart.
Other
- The Central Nervous System (CNS) includes the brain and spinal cord.
- The Peripheral Nervous System (PNS) contains nerves outside the CNS.
- Sickle cell anemia affects red blood cells, altering their shape, making them less efficient at carrying oxygen.
- Heart rate will likely increase after an anaerobic exercise.
- The difference between resting heart rate and heart rate after exercise lies in the intensity and duration of activity (increased exertion leads to increased heart rate).
