reticular Tissue
support structure
Lymph nodes
spleen
tonsils
bone marrow
liver
The structure of adipose tissue is mainly composed of fat cells also known as ____________
adipocytes
Purpose of this tissue is for energy storage, since fat or lipids is a great method for long term energy storage
adipose tissue
Densely packed collagen fibers that are parallel to each other
Cells: fibroblasts
dense regular connective tissue
Dense regular connective tissue
Provide high tensile strength along a single axis
Offers resistance to pulling forces
Ideal for structures requiring strength and elasticity in one direction
Dense regular connective tissue LOCATION
Tendons
Ligaments
Aponeuroses
Fibers are thicker and less organized
dense IRregular connective tissue
Densely packed collagen fibers arranged in a random and irregular manner
dense Irregular connective tissue
FUNCTION of connective tissue
Provide strength, support, and resistance to tension in multiple directions
Commonly found in areas subjected to stress and strain
Acts as a protective barrier against mechanical injuries
LOCATION of irregular
DPP
Dermis of skin
Periosteum
Perichondrium
_________ also known as “___________”, is a type of embryonic tissue that serves as a precursor for various types of connective tissue in the body
embryonic connective tissue
mesenchyme
Characterized by loosely arranged cells surrounded by a _______________
gelatinous extracellular matrix.
Embryonic Connective tissue function
Structural support
Cell differentiation
Organogenesis
Tissue repair
Signaling and Morphogenesis
have distinct characteristics that make them well-suited for their designated functions. They often consist of specialized cells and unique extracellular matrix compositions that provide the tissue with its specialized properties.
Specialized connective tissues
What are the Specialized connective tissue
They contribute to support,
protection,
movement,
energy storage,
blood circulation,
and immune responses.
SPMEBI
Specialized Connective tissue
Adipose Tissue
Blood Tissue
Bone Tissue
Reticular Tissue
Cartilage Tissue
A type of connective tissue that plays a crucial role in supporting and organizing various organs and tissues within the body.
reticular
It is characterized by a network of reticular fibers, which are thin, branching fibers made of collagen type III
reticular
Loose network of _________ and ___________
reticular
reticular fibers and cells
The ritecular fibers in connective tissue are known as _________________
reticular
silver stain or a reticulin stain.
Consists of __________________________________________
The reticular fibers form a delicate meshwork that provides structural support and scaffolding for other cells and tissues.
reticular
reticular fibers, fibroblasts, and a gel-like ground substance.
Function:
Structural support
Immune Support
SI
Location of reticular
Lymp nodes
Spleen
Thymus
Bone Marrow
LSTB
A type of connective tissue known as ____________
Adipose tissue
-fat tissue
is a specialized type of connective tissue that plays a crucial role in energy storage, insulation, and protection in the body. It is composed of adipocytes, which are specialized cells that store fat in the form of triglycerides
adipose tissue
It expand or shrink in response to changes in energy balance, with increased fat storage leading to the enlargement of adipocytes and expansion of adipose lobules.
Structure
Provides receive food fuel that insulates against heat loss, support and protects organs.
Function:
adipose tissue location
Skin
Kindney
Abdomen
Breast
SKAB
It consists of a mineralized extracellular matrix composed of collagen fibers, calcium phosphate, and other minerals such as magnesium and fluoride
Bone
Two types of bone tissue:
compact bone and cancellous bone
a dense and forms the outer layer of bones
Compact bone
a spongy and fills the inner part of bones
Cancellous bone
Bone connective tissue is made up of various types of cells:
Osteoblasts
Osteocytes
Osteoclasts
bone location
Location: Skull, Ribs, Sternum, Vertebral column, and Limb bones such as the Femur, Tibia, and Fibula
The functions of bone connective tissue are numerous. It provides _______________, ____________, and ___________
structural support for the body, protects vital organs, allows for movement and locomotion.
A firm, flexible, and elastic type of tissue that acts as a cushion and shock absorber between bones, facilitating smooth joint movement, as well as maintaining the shape and structure of certain organs.
cartilage
Three types of cartilage:
Hyaline Cartilage
Elastic Cartilage
Fibrocartilage
- A smooth surface that allows bones to glide over each other with minimal friction.
Hyaline Cartilage
- Provides shape and support to the external ear and epiglottis.
Elastic Cartilage
Serves as a shock absorber in weight-bearing joints,
such as the knee, and provides support to
certain tendons and ligaments.
Fibrocartilage
location of fibrocartilage
intervertebral discs, pubic symphysis, and certain tendons and ligaments
location of elastic
External ear and epiglottis
Location of hyaline
- Provides shape and support to the external ear and epiglottis.
