what tissue is this?

loose fibrous tissue/areolar tissue

give the functions of this

• Supports epithelium and internal organs.

• Forms a protective covering enclosing muscles, blood vessels, and nerves.

• Provides a reservoir of water and salts for surrounding due to its loose and fluid consistency.

where is this mostly located?

• Beneath epidermis of skin.

• Found in superficial and deep fascia.

what tissue is this?

loose adipose connective tissue

give the functions of this

• Specialized to store lipids in large vesicles.

• Protects some organs

• Insulates the body

• Reserve food

• Fat storage

where is this mostly located?

• Found wherever areolar tissue is found, but it is most often seen around the heart, kidney, and under the skin.

• Subcutaneous tissue beneath the skin

• Protects organs, such as the kidneys

• Fat depots include hips, breasts, and belly

what tissue is this?

loose reticular connective tissue

give the functions of this

• Structural support by creating and maintaining the fine networks of fibers that serve as the framework.

• Support

• Filtration

• Functions as part of the body’s defensive system.

give the location

• Forms the framework of:

  • Spleen

  • Lymph nodes

  • Bone marrow cavities

what tissue is this?

dense regular fibrous tissue

give the functions of this

• Used for structures that require a better-engineered connection between parts that are pulled with great force.

  • Tendon → attach skeletal muscle to bone.

  • Ligament → attach bone to bone at joints; more elastic than tendons.

• Flexible but strong connection

give the locations of this

• At the ends of long bones and ribs

• Larynx

• Rings in trachea and bronchi

• Entire fetal skeleton before birth

• Epiphyseal (growth) plates in long bones

what tissue is this?

fibrocartilage

give the functions of this

• Shock absorption

• Acts as a cushion within joints, where it helps manage compression forces and reduces stress placed on joints.

give the locations

• Found in structures than can withstand tension and pressure:

  • Joints

  • Vertebrae

  • Wedges found in the knee joint

  • Symphysis pubis

• Forms cushion-like discs between vertebrae of the spinal column.

what tissue is this?

elastic cartilage

give the function of this

Supports parts of your body that need to bend and move to function.

give the locations

• Found in structures in which springiness is desirable in the support material.

  • Outer ear

  • Auditory tube
