Module 3 Connective tissue Part 3 Flashcards
Are found in areas of adjacent bones. They
are covered and held together firmly by
connective tissues
Joints
The degree of movement between the bones
are defined by the
Joints
Classification of joints
- Synarthroses
- Diarthroses
it permits very limited
movements or no movement at all.
Synarthroses
permits bone to move freely
examples: elbow and knee
Diarthroses
Can be subdivided into cartilagenous and fibrous joints which depends on the tissues that binds the joints
Synarthroses
Major subtypes of Synarthroses
- Synostoses
- Syndesmoses
- Symphyses
bones are jointed only by bones. Does not
allow movement
Synostoses
only dense connective tissue unites the
bones
Syndesmoses
immobile joints. Ends are covered by pad
of fibrocartilage between articular cartilage
Symphyses
example of Symphyses
Pubic symphysis
examples of Synostoses
unite the skull bones of older adults
example of Syndesmoses
posterior region of the sacroiliac
joints
Proper alignment of the bones are maintained by the ligaments and capsule of dense connective tissue
Diarthroses
Joint cavity sealed capsule that contains synovial
fluid.it is lined by specialized connective tissue
called synovial membrane
Diarthroses
extends fold and villi to the
cavity and secretes synovial fluid which act as
lubricant
Synovial membrane
came from plasma., with higher
concentration of hyaluronan
Synovial fluid
secreted by the cells of synovial
membrane
Hyaluronan
2 specialized cells in synovial membrane
- Macrophages
- Fibroblastic synovial cells or type B cells
-like synovial cells or type A
cells
Macrophages
derived from monocytes, remove wear -and –tear
debris from the synovial fluid
Macrophages
Regulate inflammation that may take place in the
diarthrotic joints
Macrophages
Produce lots of hyaluronan and extracellular
components
Fibroblastic synovial cells or type B cells
Lubricates the joints to reduce friction, supplies
oxygen and nutrients to the articular cartilage
Fibroblastic synovial cells or type B cells
Specialized type of connective tissue
- Cartilage
- Bone
- Blood
Rbc production
Erythropoiesis
Hormone that stimulates the rbc production
Erythropoietin
Produced by the kidney
Erythropoietin
Decreased number of circulating rbc
Erythrocytopenia
Decreased in oxygen carrying capacity of rbc
Anemia
Not a disease but a symptom
Anemia
Rbc is bigger than its normal size
Macrocytic
Rbc is smaller than its normal size
Microcytic
Rbc in normal size
Normocytic
Variation in rbc shape
Poikilocytosis
Variation in rbc size
Anisocytosis
Rbc appearing darker than normal due to increased hgb content
Hyperchromic
Rbc appearing paler due to decreased hgb
Hypochromic
Rbc with normal hgb content
Normochromic
Specialized Type of Connective tissue
C. Blood
- Erythropoiesis
- Erythropoietin
- Erythrocytosis
- Erythrocytopenia
- Anemia.
- Macrocytic
- Microcytic
- Normocytic
- Poikilocytosis
- Anisocytosis
- Hyperchromic
- Hypochromic
13.Nomochromic
is pumped by the rhythmic contractions
of the heart flowing in a single direction at a
close circuit called circulatory system.
Blood
A specialized connective tissue has
fluid extracellular matrix known as plasma, with
suspended cellular elements
General function of specialized Type of Connective tissue
C. Blood
- Transport
- Maintain/regulate-Homeostasis
- Serve as body’s defense mechanism against
infection
Specialized type of CT
C. Blood
Transports
– oxygen & carbon dioxide
– nutrients to tissues and organs
– hormones to target organs
