LOCATION: Under skin and between muscles. (Skin- Light tissue under the stratified squamous cells)

IDENTIFICATION: Delicate, thin membranes with fibroblasts, collagenous & elastic fibers.

S/F: loose, open-weave structure with randomly oriented collagen, elastic, and reticular fibers, abundant ground substance, and numerous blood vessels directly support its functions of binding, support, nourishment, defense, and flexibility.

# data[].attributes.body
LOCATION: under the skin, around internal organs, within bone marrow, and distributed between muscles.

IDENTIFICATION: White/clear cells used to store fat

S/F: large lipid droplet, which efficiently stores energy in the form of fat, providing insulation and cushioning organs.

# data[].attributes.body
LOCATION: Spleen- network of fibers around cells

IDENTIFICATION: Thin, collagenous fibers, makes 3-D networks for organs

S/F: This fine meshwork provides an organized environment for immune cell activity and interaction, facilitating their proliferation and movement, thus enhancing the body's immune response.

# data[].attributes.body
LOCATION: Tendons and ligaments

IDENTIFICATION: Closely-packed collagenous fibers with fine network of elastic fibers (White Fibrous- Clear, wavy, on outside)

S/F: the parallel arrangement of tightly packed collagen fibers allows it to withstand high tensile stress in a single direction, as seen in tendons and ligaments

KEY: fibroblasts are circled in black.

# data[].attributes.body
LOCATION: ends of bones, rings of trachea (Frog Toe Bone, Trachea)

IDENTIFICATION: very fine collagenous fibers

S/F: smooth, glassy matrix with collagen fibers embedded in a gel-like ground substance, which allows it to provide a low-friction, resilient, and flexible surface for joints while supporting and reinforcing other tissues

KEY: lacunae are in black circles; perichondrium is absent in this image.

# data[].attributes.body
LOCATION: ears & larynx

IDENTIFICATION: dense network of elastic fibers

S/F: allow organs and tissues to stretch and then recoil to their original shape. This is achieved through a matrix of elastin and collagen fibers, which provides both elasticity and tensile strength

KEY: Black arrows demonstrate the perichondrium, and the lacunae are inside the white circle.

# data[].attributes.body
LOCATION: intervertebral discs

IDENTIFICATION: tough, many collagenous fibers, shock absorber

S/F: strength and shock absorption through its combination of dense collagen fibers and a cartilage matrix. The dense, interwoven bundles of Type I collagen fibers make it durable and resistant to compression, while the presence of chondrocytes within the cartilage matrix allows for resilience

KEY: lacunae are circled in black

# data[].attributes.body
LOCATION: Ground Bone

IDENTIFICATION: the lamella, central canal, lacunae, osteocyte, osteon, canaliculi

S/F: strength comes from an extracellular matrix containing organic collagen fibers for flexibility and inorganic mineral crystals (like hydroxyapatite) for hardness. The arrangement of bone cells within lacunae, connected by tiny canals called canaliculi for nutrient and waste exchange, supports the living tissue within the hardened matrix

KEY: Orange O=Osteon

Green L=Lacunae

Blue CC=Central Canal

Red L=Lamella

Yellow C=Canaliculi

# data[].attributes.body
LOCATION: soft, spongy center of bones called bone marrow

IDENTIFICATION: Erythrocyte vs. Leukocyte

S/F: plasma and specialized cells, is directly related to its function as a transport and defense system. Red blood cells, with their biconcave shape, maximize oxygen transport, while white blood cells fight infection, and platelets, as cell fragments, initiate clotting to prevent blood loss. The plasma's proteins transport substances and help maintain osmotic pressure and immune defense

KEY: The white blood cells are circled in black, the red blood cells are circled in red.
