Immunity
These cells directly kill cells that are infected with intracellular pathogens
Cytotoxic T Cells (CD8).
This cell predominates in acute inflammation.
Neutrophils
These large, multi-nucleated cells are responsible for the resorption of bone.
Osteoclasts.
This mechanism of cartilage growth is typically described as 'growth from within'.
Interstitial Growth.
This type of immunity is acquired through a vaccination.
Artificially Acquired Active Immunity.
What is the name of the progenitor pathway of Natural Killer cells and which immune defence they are involved in.
Lymphoid progenitor
Innate immunity
This is the the connective tissue layer located on the outside of bones.
Periosteum.
This type of cartilage would be found within intervertebral disks and consists of Type 1 Collagen.
Fibrocartilage.
These cell types present pathogens on MHCII molecules to Helper T Cells (CD4).
Professional Antigen Presenting Cells (pAPCs)
- Macrophages
- Dendritic Cells
- B Lymphocytes
This reaction occurs within minutes of an allergen response.
Type I Hypersensitivity Reaction.
This is where the secondary ossification centres form.
Epiphyses.
This component of the cartilage matrix traps water and allows for shock absorption.
Ground Substance (GAGs).
This complement fragment is the most important opsonization.
C3b.
This hypersensitivity reaction is caused by the deposition of antigen/antibody/Complement complexes in blood vessels and tissues.
Type III Hypersensitivity (Immune Complex Disease).
This joint type is the only multiaxial joint in the human body.
Ball-and-Socket Joint.
This layer is found in the cartilage perichondrium and contains Type 1 Collagen and Fibroblasts.
Outer Fibrous Layer.
Naïve B cells directly enter the cortex of the lymph node through these specific vessels
High Endothelial Venules (HEV)
Which is the first vascular event in acute inflammation?
Vasodilation
This component of the bone matrix makes up 35% and gives bone its flexibility and resilience.
Organic Bone Matrix.
This term describes clusters of chondrocytes within cartilage that originate from a single parent cell through mitotic division, surrounded by a shared territorial matrix.
Isogenous groups.
