#1
Which type of bone tissue provides strength and support?
Compact bone
ExplanationCompact bone provides strength and support due to its dense structure.
#2
What is the function of yellow bone marrow?
Stores fat
ExplanationYellow bone marrow functions primarily as a fat storage tissue.
#3
Which bone in the human body is commonly referred to as the collarbone?
Clavicle
ExplanationThe clavicle, commonly known as the collarbone, connects the shoulder to the chest.
#4
Which bone is not part of the axial skeleton?
Radius
ExplanationThe radius is not part of the axial skeleton but is instead a bone of the forearm.
#5
Which bone is not part of the appendicular skeleton?
Vertebra

#6
Where can hyaline cartilage be found in the body?
Nose
ExplanationHyaline cartilage is found in the nose, providing structural support and flexibility.
#7
What is the primary function of osteoblasts?
Produce new bone tissue
ExplanationOsteoblasts are responsible for the formation of new bone tissue during bone growth and repair.
#8
Which cells are responsible for bone resorption?
Osteoclasts
ExplanationOsteoclasts break down bone tissue during bone remodeling and calcium regulation.
#9
What is the purpose of the periosteum?
To attach tendons and ligaments to bone
ExplanationThe periosteum serves as an attachment point for tendons and ligaments, as well as a source of new bone cells.
#10
Which type of joint allows the most movement?
Ball and socket joint
ExplanationBall and socket joints allow for the greatest range of motion in multiple directions.
#11
Which hormone regulates calcium levels in the blood?
Parathyroid hormone
ExplanationParathyroid hormone regulates calcium levels by stimulating the release of calcium from bones.
#12
Which hormone stimulates bone growth during childhood and adolescence?
Growth hormone
ExplanationGrowth hormone stimulates bone growth by promoting the proliferation of bone cells during childhood and adolescence.
#13
Which bone forms the heel of the foot?
Calcaneus
ExplanationThe calcaneus, also known as the heel bone, provides support and attachment for various foot muscles.
#14
Which hormone inhibits bone resorption and stimulates calcium deposition in bone?
Calcitonin
ExplanationCalcitonin inhibits bone resorption by osteoclasts and promotes calcium deposition in bone, helping to regulate blood calcium levels.
