Connective Tissue Flashcards
What is the only avascular connective tissue?
Cartilage
Types of Loose connective (connective proper)
Areolar, Adipose
Characteristics of Loose connective
Large intercellular space, most abundant, surrounds and cushions organs, and Nucleus and cytoplasm pushed to the side of the cell by large fat droplet
Loose connective location-Adipose
subcutaneous layer of the skin and surrounding all body organs and the eyeballs.
Loose connective location- Aerolar
underlines most layers of epithelium binds skin to underlying muscles and fills space between muscles
Dense connective description
Dense fibrous connective tissue is composed of a tightly packed matrix of collagen fibers and fibroblasts that are either regularly or irregularly arranged.
Dense connective- Irregular Arrangement description
Occurs in sheets found where multi-directional tensions are encountered
Dense connective- Irregular Arrangement location
Lower layer of the skin (Dermis) White layer of the eyeball
Dense Connective- Regular arrangement description
Fibers are arranged in orderly parallel fashion Adapted for tension in one direction
Dense connective- Regular arrangement location
Tendons which bind muscle to bone, and Ligaments- ligaments bind to bone
Supportive Connective- types
Cartilage and bone
characteristics of cartilage
Avascular, can withstand tremendous forces, Extremely dense network of collagen and elastic fibers firmly embedded in a jelly-like intercellular ground substance.
Chondrocytes
mature cartilage cells
Perichondrium
dense connective tissue covering that surrounds the surface of cartilage
Cartilage tissue types
Hyaline, Fibrocartilage, elastic cartilage
Hyaline description and location
Covers ends of long bones, reduces friction at joints, forms costal cartilage at ends of ribs, makes up most of the embryonic skeleton, makes up nose and ribs.
Fibrocartilage description and location
Main role is shock absorption- location: intervertebral disks, public symphysis, menisci of knee
Elastic cartilage description and location
Structural, provides strength, rigidity, and maintains shape of some organs. Location- larynx, ear, trachea, auditory tubes, and epiglottis
Bone or Osseous tissue characteristics
Maintained by specialized cells: osteoblasts which build up bone tissue, osteocyte, osteoclast
Function of bone or osseous tissue
Structure of the body, movement, storage of minerals, production of all blood cells, protectin
Classification of bone or osseous tissue
Spongy bone, compact bone
Erythrocytes
red blood cells
Leukocytes
white blood cells
Thrombocytes
platelets
Why is blood considered a connective tissue
It helps support tissues and connects them together since it’s in every system
