Study Notes
Skeletal System Review
-
Question 1: Which function of the skeletal system is crucial in a car accident?
- Answer: Protection of internal organs.
- Reasoning: The skeletal system acts as a protective shield (like the rib cage for the heart/lungs or the skull for the brain) during trauma.
-
Question 2: How can bone tissue be described?
- Answer: Dense, hard connective tissue.
- Reasoning: Bone is a strong, hard tissue, but it's part of the connective tissue family, providing support and protection to the body.
-
Question 3: What is needed for bones to function?
- Answer: Red marrow.
- Reasoning: Red marrow is essential for blood cell production (hematopoiesis).
Other Body System Review
-
Question 4: What is yellow marrow?
- Answer: An area of fat storage.
- Reasoning: Yellow marrow acts as an energy reserve within the medullary cavities of long bones.
-
Question 5: What structures make up the skeletal system?
- Answer: Bones and cartilage.
- Reasoning: Bones provide the framework, and cartilage provides flexibility/cushioning in joints.
-
Question 6: When can calcium not be absorbed from the small intestine?
- Answer: If vitamin D is lacking.
- Reasoning: Vitamin D is essential for calcium absorption.
-
Question 7: What element triggers muscle contraction directly?
- Answer: Calcium (Ca++).
- Reasoning: Calcium ions bind to proteins in muscle fibers, enabling contraction.
-
Question 1: (Regarding Urinary System) How does the position of the right kidney differ from the left kidney?
- Answer: The right kidney is slightly lower than the left kidney.
- Reasoning: This is because the liver, on the right side of the body, pushes the right kidney downwards.
-
Question 2: (Regarding Urinary System) What is the functional unit of the kidney?
- Answer: The nephron.
- Reasoning: Nephrons are microscopic structures that filter blood and form urine; they're the kidneys' primary working units.
-
Question 3: (Regarding Urinary System) What's not true about the structure and function of the urinary system?
- Answer: The kidneys are at equal heights within the pelvic cavity.
- Reasoning: The right kidney is slightly lower than the left due to the liver's position.
-
Question 4: (Regarding Urinary System) What is not an organ of the urinary system?
- Answer: Liver.
- Reasoning: The liver is part of the digestive system; the urinary system includes the urethra, ureter, kidneys, and bladder.
-
Question 5: (Regarding Urinary System) Which is not a function of the kidneys?
- Answer: They release a majority of wastes into the bloodstream.
- Reasoning: Kidneys filter wastes out of the blood and excrete them in urine, not returning them to the bloodstream.
-
Question 6: (Regarding Urinary System) What organ system excretes nitrogenous wastes?
- Answer: The urinary system.
- Reasoning: The urinary system removes nitrogenous wastes (like urea) from the body via urine.
-
Reproductive System (Question 1): What are male gametes called?
- Answer: Sperm.
-
Reproductive System (Question 2): Where does spermatogenesis (sperm production) take place?
- Answer: Seminiferous tubules.
-
Reproductive System (Question 3): What are the female gonads called?
- Answer: Ovaries.
-
Other Reproductive and Urinary System Questions:
- The timing of puberty can be influenced by factors like genes, stress levels, and body fat, as these impact hormone production.
- Fertilization typically occurs in the uterine tube (fallopian tube).
- The testes are the male gonads and sperm is the male gamete.
- Secondary sex characteristics develop during puberty. E.g., breast development and facial hair growth.
-
Nervous System (Question 1): Which cavity holds a part of the central nervous system?
- Answer: Cranial cavity.
-
Nervous System (Question 2): Which cavity contains a component of the central nervous system?
- Answer: Cranial cavity (Same as Question 1).
-
Nervous System (Question 3): What part of a neuron transmits electrical signals?
- Answer: Axon.
-
Nervous System (Question 4): What term describes a bundle of axons in the peripheral nervous system?
- Answer: Nerve.
-
Nervous System (Question 5): Which part of a neuron contains the nucleus?
- Answer: Soma (cell body).
-
Nervous System (Question 6): What type of glial cell is a resident macrophage in the CNS?
- Answer: Microglia.
-
Nervous System (Question 7): What macromolecules are components of myelin?
- Answer: Lipids and proteins.
-
Nervous System (Question 8): If a thermoreceptor senses temperature, what does a chemoreceptor sense?
- Answer: Molecules (chemical stimuli).
-
Nervous System (Question 9): Which ion causes depolarization in a neuron?
- Answer: Sodium (Na+).
-
Nervous System (Question 10): What state does voltage-gated Na+ channels open at?
- Answer: Threshold.
-
Nervous System (Question 11): What do mechanically gated channels respond to?
- Answer: Physical stimuli (e.g., pressure, stretch).
-
Other Nervous System Questions:
- Acetylcholine is the neurotransmitter released at the neuromuscular junction.
- A stroke occurs when blood flow to the brain is disrupted (due to a clot or bleeding).
- Afferent neurons carry sensory signals to the CNS. Efferent neurons carry motor signals from the CNS.
- A nerve fiber typically refers to an axon
