Per:5
Epithelial Tissue
Simple Epithelium
1 layer of cells
Stratified Epithelium
multiple layers of cells
Squamos
flattened and cell like
Cubiodal
box-like, cube
Columnar
tall- rectangle/ colunm
Connective Tissues
Areolar Tissue
support and flexibility; it's located under the skin and wraps around blood vessels and nerves.
Adipose Tissue
Fat is stored in the body to provide insulation and protect organs; it can be found beneath the skin
Reticular Tissue
a helpful structure for soft organs such as the liver, spleen, and lymph nodes.
Hyaline Cartilage
is smooth and has a glassy appearance is located on the surfaces of joints, in the nose, and in the trachea. It helps to cushion and support these areas.
Regular Tissue
Made up of closely packed collagen fibers that run parallel to each other, this tissue is found in tendons and ligaments, giving them a strong, rope-like durability.
Irregular Tissue
dermis of the skin has collagen fibers that are arranged, helps give strength in various directions.
Elastic Tissue
a lot of elastin fibers, helps tissues to stretch and bounce back. Fibers are found in the walls of arteries and in some ligaments.
Elastic Cartilage
higher amount of elastin fibers, which gives it flexibility; this type of tissue is located in the ear
Fibrocartilage
Dense, tough cartilage that absorbs shock; found in intervertebral discs, pubic, and the knee.
Compact Bone
tough and solid material that makes up the outer layer of bones; it gives support and keeps them safe.
Spongy Bone
The ends of long bones have a lighter and more porous type of bone tissue, this area is where bone marrow is located, and it's responsible for producing blood cells.
Muscular Tissues
Skeletal
muscle tissue is a type of voluntary muscle that connects to bones and helps us move our bodies. It has a striped look because of the way the actin and myosin filaments are arranged in an organized pattern.
Cardiac Muscle
is a type of involuntary muscle that is only located in the heart. It has a striated appearance similar to skeletal muscle, but it also has special characteristics that help it perform its job of contracting rhythmically and continuously.
Smooth Muscle
involuntary muscle that is not striated and is located in the walls of hollow organs like the intestines, blood vessels, bladder, and uterus.
Nervous Tissue
Axon
A long, thin signal that carries signals from the neuron to other neurons, muscles, or glands.
Cell Body
Has the nucleus and organelles inside
contains the brain, spinal cord, and nerves
Glands
Endocrine Glands
Glands that release hormones straight into the blood without using ducts.
Ex: Pancreas, Thyroid, Adernal
Functions: Control growth, metabolism, reproduction, and mood by producing hormones.
Exocrine Glands
Glands that release substances through tubes to the surface of an organ or skin.
Ex: Sweat Glands, Salivary Glands, Stomach Function: breaks down food, keeping things moist, controlling temperature, and providing safety.
Membranes
Serous Membrane
Thin layers that cover the inside of body cavities and the organs inside them.
Mucous Membrane
Layers that cover body spaces and tubes that connect to the outside.
Cutaneous Membrane
The skin is the biggest organ in the body
