Physiology - Assignment 1 :Skeletal Tissues and Skeletons

QuestionAnswer
What is the primary function of skeletal tissues? Skeletal tissues primarily provide structural support and protect vital organs in the body.
What is the significance of the epiphyseal plate in bone growth? The epiphyseal plate, also known as the growth plate, is responsible for longitudinal bone growth in children and adolescents.
What are the two main types of skeletal tissues in the human body? The two primary types of skeletal tissues are compact bone and spongy bone.
What is the function of hyaline cartilage, and where is it found? Hyaline cartilage provides support and flexibility and is found in areas like the nose, trachea, and articular surfaces of joints.
How does elastic cartilage differ from hyaline cartilage, and where is it located? Elastic cartilage contains elastic fibers, giving it more flexibility, and is found in the external ear and epiglottis.
Where is fibrocartilage typically located, and what is its function? Fibrocartilage is found in structures like intervertebral discs and the pubic symphysis, providing shock absorption and support.
What are the primary functions of bones in the human body? Bones provide structural support, protection, aid in movement, house bone marrow for blood cell production, and store minerals like calcium.
What is the role of osteoblasts in bone tissue? Osteoblasts are responsible for building new bone tissue.
Which cells are involved in bone resorption and remodeling? Osteoclasts are responsible for breaking down and remodeling bone tissue.
Why is continuous remodeling of bone tissue important for the body? Continuous remodeling helps repair damaged bone, maintain calcium levels, and adapt to changing stresses.
What is the axial skeleton, and what are some examples of axial bones? The axial skeleton includes bones along the body's central axis, such as the skull, vertebral column, and ribcage.
How does the appendicular skeleton contribute to human movement? The appendicular skeleton includes bones of the limbs, pelvis, and shoulder girdle, facilitating movement and mobility.
How does the human skeleton differ from the skeletons of other vertebrates? The human skeleton is adapted for an upright posture and bipedal locomotion, unlike the quadrupedal skeletons of many vertebrates.
What is the primary function of an endoskeleton? An endoskeleton provides internal support and structure for the body while allowing for flexibility and growth.
What are some characteristics of an exoskeleton, and which animals typically have one? An exoskeleton is a hard, external covering found in arthropods like insects and arachnids, providing protection and support.
How does the axial skeleton protect vital organs? The axial skeleton includes the skull, which protects the brain, and the ribcage, which safeguards the heart and lungs.
How do bones heal after a fracture, and what factors influence the healing process? Bones heal through a process of fracture hematoma formation, callus formation, and remodeling. Factors like age and nutrition can influence healing.
What is the impact of skeletal growth plates on the development of an individual? Growth plates are responsible for longitudinal growth in bones and, when they close, signal the end of vertical bone growth.
How does the presence of cartilage in the skeleton affect bone development and growth? Cartilage serves as a template for bone development, allowing bones to grow and adapt in size and shape during development.
What is the importance of bone marrow in the skeletal system? Bone marrow produces red blood cells, white blood cells, and platelets, crucial for blood cell formation and immune function.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
