Tissues

A set of flashcards covering key vocabulary and concepts related to human tissue types as discussed in the lecture.

Epithelial Tissue

A type of tissue that covers organs and the body and lines body cavities and hollow organs.

Connective Tissue

The most abundant tissue type that supports, binds, and protects other tissues.

Muscle Tissue

Tissue responsible for the movement of the body and its parts, consisting of skeletal, smooth, and cardiac muscle.

Nervous Tissue

Tissue that makes up the nervous system and is responsible for transmitting nerve impulses.

Squamous Epithelium

Epithelial tissue consisting of a single layer of flat cells.

Cuboidal Epithelium

Epithelial tissue made up of a single layer of cube-shaped cells.

Columnar Epithelium

Epithelial tissue that consists of a single layer of elongated cells.

Simple Squamous Epithelium

A single layer of flat cells, allowing substances to pass easily through.

Stratified Squamous Epithelium

Multiple layers of flat cells, providing protection.

Pseudostratified Columnar Epithelium

Single layer of elongated cells with nuclei at different levels, often with cilia.

Simple Cuboidal Epithelium

A single layer of cube-shaped cells that line kidney tubules and some glands.

Simple Columnar Epithelium

Single layer of elongated cells that may possess cilia or goblet cells.

Transitional Epithelium

Epithelial tissue that can change shape, found in the urinary bladder.

Glandular Epithelium

Cells specialized to produce and secrete substances.

Endocrine Glands

Glands that are ductless and secrete hormones directly into the bloodstream.

Exocrine Glands

Glands that have ducts and secrete substances onto the surface or into cavities.

Merocrine Glands

Glands that secrete fluid products without loss of cellular material.

Apocrine Glands

Glands that lose portions of their cells during secretion.

Holocrine Glands

Glands that release entire cells filled with secretory products.

Connective Tissue Proper

Tissues that support and connect other tissues, including loose and dense connective tissue.

Collagenous Fibers

Thick fibers composed of collagen that provide strength.

Elastic Fibers

Fibers composed of elastin that allow tissues to stretch and recover.

Reticular Fibers

Thin, branched fibers that form supportive networks.

Fibroblasts

Common fixed cells in connective tissue that produce fibers.

Macrophages

Wandering cells that are phagocytic and important in defense.

Mast Cells

Fixed cells that release substances such as histamine and heparin.

Loose Connective Tissue

Connective tissue that is more flexible and contains fewer fibers.

Adipose Tissue

Connective tissue that stores fat and insulates the body.

Dense Regular Connective Tissue

Tissue made of tightly packed fibers that provides strength in one direction.

Dense Irregular Connective Tissue

Tissue with fibers arranged in multiple directions, providing strength in various directions.

Reticular Connective Tissue

Tissue composed of reticular fibers, supporting the internal structure of organs.

Elastic Connective Tissue

Connective tissue containing numerous elastic fibers, allowing for stretch.

Bone Tissue

A type of connective tissue with a solid matrix that supports and protects organs.

Cartilage

A type of connective tissue with a rigid matrix and chondrocytes located in lacunae.

Hyaline Cartilage

The most abundant type of cartilage, found in the nose, respiratory passages, and at the ends of bones.

Elastic Cartilage

Cartilage that is flexible and found in structures like the ear.

Fibrocartilage

Tough cartilage found in intervertebral discs and joints.

Blood

A fluid connective tissue with a matrix called plasma and various types of cells.

Erythrocytes

Red blood cells responsible for transporting oxygen.

Leukocytes

White blood cells that are involved in immune responses.

Thrombocytes

Platelets involved in blood clotting.

Skeletal Muscle

Striated muscle under voluntary control that attaches to bones.

Smooth Muscle

Involuntary muscle found in the walls of organs and blood vessels.

Cardiac Muscle

Striated muscle found only in the heart, involuntary and includes intercalated discs.

Neurons

Basic cells of nervous tissue that transmit nerve impulses.

Neuroglial Cells

Supporting cells within nervous tissue that aid neurons.

Serous Membrane

Membranes lining body cavities that do not open to the outside.

Mucous Membrane

Membranes lining tubes and organs that open to the outside world.

Cutaneous Membrane

The skin, which covers the exterior of the body.

Synovial Membrane

Connective tissue lining the joints, secreting synovial fluid.

Extracellular Matrix (ECM)

The non-cellular component of tissues, providing structural and biochemical support.

Carcinoma

A type of cancer originating from epithelial tissue.

Sarcoma

A type of cancer arising from connective tissue.

Melanoma

A type of skin cancer that arises from melanocytes.

Lymphoma

A cancer of the lymphatic system.

Leukemia

A cancer of blood-forming tissues.

Collagen Disorders

Disorders related to improper collagen formation or degradation.

Chondrodysplasia

A genetic disorder causing abnormal cartilage development.

Dystrophic Epidermolysis Bullosa

A condition caused by defective collagen affecting skin integrity.

Hereditary Osteoarthritis

A joint disorder caused by a genetic alteration in collagen.
