Question

What tissue has lacunae, calcium salts, and blood vessels? Select one: a. fibrocartilaginous tissue b. areolar tissue c. bone (osseous tissue) d. cartilage tissue

Answer 1

Bone (osseous tissue) has lacunae, calcium salts, and is highly vascularized, distinguishing it from other tissue types like cartilage and areolar tissue.

Step-by-step explanation:

The tissue characterized by having lacunae, calcium salts, and blood vessels is bone (osseous tissue). Bone tissue is a type of connective tissue that has a rigid extracellular matrix with mostly collagen fibers embedded in a mineralized ground substance containing hydroxyapatite—a form of calcium phosphate. This combination contributes to the bone's hardness and its ability to support the body and protect internal organs.

Within this matrix, bone cells, or osteocytes, reside in small cavities known as lacunae. Bone tissue is highly vascularized, meaning it has a good blood supply, which is necessary for nutrient delivery and waste removal. This vascularization also allows bone tissue to recover from injuries more efficiently than non-vascularized tissues like cartilage.

Answer 2

c. bone (osseous tissue)

Step-by-step explanation:

The extracellular matrix of the bone tissue consists of an organic component and an inorganic component.

The organic component includes Collagen , proteoglycans and glycoprotiens, While the inorganic component contains calcium and phopsphorus. The cells are present in the lacunae situated betwen the lamellae and contain a number of oblong spaces.

It also contains blood vessels as a typical long bons is supplied by a nutrient artery , periosteal vessels and epiphyseal arteries.

Hence C is the right answer.
