Tissue Types
What type of tissue lines surfaces and forms glands?
Epithelial tissue.
What flat, scale‑like epithelial cells form this type of epithelium?
Simple squamous epithelium.
What connective tissue has a gel‑like matrix and many fiber types; it “packs” organs?
Areolar connective tissue.
What muscle type is voluntary and striated?
Skeletal muscle.
What cells conduct electrical impulses?
Neurons.
What type of tissue has abundant extracellular matrix and includes bone, cartilage, and blood?
Connective tissue.
What epithelium is found in the kidney tubules and has cube‑shaped cells?
Simple cuboidal epithelium.
What fibers provide tensile strength and are the most abundant protein in the body?
Collagen fibers.
What muscle type is striated, branched, and contains intercalated discs?
Cardiac muscle.
What supportive cells outnumber neurons?
Neuroglial cells or glial cells.
What long, excitable cells contract to produce movement?
Muscle fibers
What tall, column‑shaped cells with goblet cells are characteristic of this epithelium?
Simple columnar epithelium.
What connective tissue stores energy and insulates the body?
Adipose tissue.
What muscle type is non‑striated and found in the walls of organs?
Smooth muscle.
What long extension of a neuron that carries signals away from the cell body?
Axon.
What tissue contains neurons and glial (neuroglia) cells?
Nervous tissue.
What epithelium appears layered but every cell touches the basement membrane?
stratified columnar epithelium
Chondrocytes in lacunae are found in what tissue type?
Cartilage
What structures inside muscle fibers contain actin and myosin?
Myofibrils.
What part of the neuron receives incoming signals?
Dendrites.
Name the four major tissue types found in animals.
1. Epithelial
2. Connective
3. Muscle
4. Nervous
What epithelium is specialized to stretch, such as in the bladder?
Transitional epithelium.
Blood is considered what type of tissue because it has a matrix and originates from mesenchyme?
Connective tissue.
Unlike connective tissue fibers, what “fibers” are actually whole cells?
Muscle fibers.
Nervous tissue developes from what embryonic germ layer?
Ectoderm.
