To produce hormones
To conduct nerve impulses
To contract and relax
Which statement best describes macrophages in connective tissue?
They are always fixed in one place.

They are only found in bones
They are not flexible at all
Which of the following best describes the function of mast cells in connective tissue?
Form delicate supportive networks within tissues

Provide elastic quality to parts that stretch
A patient has a connective tissue disorder that affects the ability to hold structures together. Which component is most likely affected?

Elastic fibers
Mast cells
Ground substance
Why is collagen vulnerable to disruption?
It is a very flexible protein
It has a very precise structure
It is not found in connective tissues
It is made up of carbohydrates
Which condition is characterized by asymmetric and too wide collagen chains, leading to stunted growth and deformed joints?
Marfan syndrome
Osteoporosis
Chondrodysplasia
Scurvy
Explain how areolar connective tissue supports epithelial cells.
By producing hormones for epithelial cells
By nourishing nearby epithelial cells with blood vessels
By forming bone matrix
By storing fat for epithelial cells
Which structure in adipose connective tissue stores fat?
Lipid inclusions of adipocytes
Nuclei of adipocytes
Capillaries
Mitochondria
Which of the following is a primary component of reticular connective tissue?
Reticular fibers
Adipocytes
Osteocytes
Chondrocytes
What is the function of macrophages in reticular connective tissue?
Engulf and digest cellular debris and pathogens
Produce collagen fibers
Store fat
Transport oxygen
How do leukocytes contribute to the function of reticular connective tissue?
They participate in immune responses.
They secrete hormones.
They store calcium.
They produce cartilage.
Why does cartilage heal slowly?
It is constantly being replaced
It lacks blood supply
It is exposed to high pressure
It is made of hard minerals
Where can hyaline cartilage be found in the human body? (Select the best answer)
External ear and larynx
Ends of bones in joints, nose, and respiratory passages
Skin and tendons
Ligaments and blood vessels
Which type of cartilage is shown in the provided images?
Hyaline cartilage
Elastic cartilage
Fibrocartilage
Articular cartilage
Explain how the arrangement of chondrocytes within lacunae supports the function of hyaline cartilage.
The arrangement allows for even distribution of mechanical stress and efficient nutrient diffusion, supporting cartilage resilience and function.
The arrangement increases the density of blood vessels in the tissue.
The arrangement enhances the storage of fat within the cartilage.
The arrangement allows for rapid electrical signaling between cells.
What is one of the main functions of fibrocartilage in the body?
Energy storage
Shock absorption
Oxygen transport
Hormone production
Which of the following best explains why fibrocartilage is used in the pads of the knee and pelvic girdle?
It is highly flexible and can stretch easily
It is very tough and acts as a shock absorber
It produces hormones needed for joint movement
It is responsible for immune defense in joints
In the context of fibrocartilage, what are lacunae?
Spaces that house chondrocytes
Protein fibers
Blood vessels
Nerve endings
Explain how the structure of fibrocartilage contributes to its function in the body.
The dense collagen fibers provide tensile strength, while chondrocytes in lacunae help maintain the matrix, making fibrocartilage ideal for resisting compression and tension.
The presence of adipocytes allows for fat storage, making fibrocartilage a major energy reserve.
The high mineral content makes fibrocartilage the main tissue for bone formation.
The abundance of nerve endings makes fibrocartilage highly sensitive to pain.
Which of the following is the most rigid connective tissue in the human body?
Bone
Cartilage
Adipose tissue
Blood
Explain how the arrangement of osteons contributes to the strength of compact bone.
Osteons are randomly arranged, providing flexibility.
Osteons are arranged in parallel, allowing bones to resist bending and compression.
Osteons are arranged in layers, which makes bones lighter.
Osteons are arranged in a circular pattern, which increases bone porosity.
Which cells are responsible for depositing the matrix in lamellae (layers) in compact bone?
Osteoblasts
Chondrocytes
Fibroblasts
Adipocytes
Which of the following best describes the arrangement of lamellae in compact bone?
Lamellae are randomly scattered throughout the bone
Lamellae occur in rings around central canals
Lamellae are only found at the bone surface
Lamellae are arranged in parallel lines
Which structure in compact bone contains blood vessels and nerves?
Lamella
Central canal
Lacuna
Canaliculi
Where is spongy bone typically found in long bones?
In the ends of long bones
On the surface of long bones
In the middle of long bones
Only in short bones
