#1
Which cell type is responsible for bone resorption?
Osteoclast
ExplanationOsteoclasts are responsible for breaking down bone tissue.
#2
What is the function of yellow bone marrow?
Energy storage
ExplanationYellow bone marrow primarily serves as a site for fat storage.
#3
Which bone is not part of the axial skeleton?
Femur
ExplanationThe femur is part of the appendicular skeleton, not the axial skeleton.
#4
What is the function of osteocytes?
Maintaining bone matrix
ExplanationOsteocytes maintain the bone matrix and detect mechanical stress.
#5
What type of bone tissue forms the hard outer shell of bones?
Compact bone
ExplanationCompact bone forms the hard, outer shell of bones, providing strength and support.
#6
Which bone marking serves as a site for muscle or ligament attachment?
Tuberosity
ExplanationTuberosities are bone markings that serve as attachment sites for muscles or ligaments.
#7
Which type of bone is primarily composed of trabecular bone tissue?
Flat bone
ExplanationFlat bones primarily consist of trabecular bone tissue.
#8
Which hormone stimulates osteoclast activity and calcium release from bone?
Parathyroid hormone
ExplanationParathyroid hormone stimulates osteoclasts to release calcium from bone.
#9
Which type of cartilage is found in the intervertebral discs?
Fibrocartilage
ExplanationFibrocartilage is found in intervertebral discs, providing both strength and flexibility.
#10
Which type of bone growth occurs at the epiphyseal plate?
Interstitial growth
ExplanationEpiphyseal plates allow for interstitial growth, increasing bone length.
#11
Which bone is not part of the human appendicular skeleton?
Sternum
ExplanationThe sternum is part of the axial skeleton, not the appendicular skeleton.
#12
Which bone is commonly known as the collarbone?
Clavicle
ExplanationThe clavicle is commonly referred to as the collarbone.
#13
Which structure connects osteocytes within the bone tissue?
Canaliculi
ExplanationCanaliculi are tiny channels that connect osteocytes and allow for nutrient exchange.
#14
What is the structural unit of compact bone tissue?
Osteon (Haversian system)
ExplanationThe osteon, or Haversian system, is the basic unit of compact bone tissue.
#15
Which histological feature is characteristic of elastic cartilage?
Numerous elastic fibers
ExplanationElastic cartilage contains abundant elastic fibers, providing flexibility.
