Cardiac Muscle

Cardiac Muscle

A type of involuntary muscle found in the heart, characterized by striations and intercalated discs.

Striations

Alternating light and dark bands found in skeletal and cardiac muscle fibers, indicating the presence of organized myofibrils.

Intercalated Discs

Specialized connections between cardiac muscle cells that facilitate synchronized contraction.

Endomysium

A thin layer of connective tissue that surrounds individual muscle fibers.

Skeletal Muscle

A type of striated muscle that is under voluntary control, attached to bones.

Smooth Muscle

Involuntary muscle found in the walls of hollow organs, lacking striations.

Neuropil

A dense network of interwoven axons, dendrites, and glial cells in the nervous system.

Glial Cells

Supportive cells in the nervous system that provide insulation, nutrients, and support to neurons.

Connective Tissue

A diverse group of tissues that support, bind, and protect other tissues and organs in the body.

Adipose Tissue

A type of connective tissue that stores fat and provides insulation and cushioning.

Hyaline Cartilage

A type of cartilage characterized by a glossy, smooth appearance, found in joints and respiratory structures.

Osteocyte

A mature bone cell that maintains the bone matrix.

Canaliculi

Small channels in bone that allow for communication and nutrient exchange between osteocytes.

Central Canal

The central channel in an osteon that contains blood vessels and nerves.

Simple Squamous Epithelium

A single layer of flat cells that facilitates diffusion and filtration.

Simple Cuboidal Epithelium

A single layer of cube-shaped cells, often involved in secretion and absorption.

Ciliated Simple Columnar Epithelium

A type of epithelium with cilia on the apical surface, found in the respiratory tract.

Pseudostratified Columnar Epithelium

A single layer of cells that appears stratified due to varying cell heights, often ciliated.

Stratified Squamous Epithelium

Multiple layers of flat cells that protect underlying tissues from abrasion.

Elastic tissue

Reticular tissue

Red blood cell

Erythrocytes

White blood cells

Leukocytes

Neutrophil (blobby nucleus)

Lymphocyte(fuzzy purple)

Platelets (tiny purple)

Dense irregular connective tissue

Elastic fibers

Stretchy

Regular dense connective tissue

Osteon

Lamellae of Osteon

Transitional epithelium

made up of several layers of cells that become flattened when stretched

Fibrocartilage

transitional tissue that derives from mesenchymal tissue that lacks a perichondrium and has structural and functional properties between that of dense fibrous connective tissue and hyaline cartilage.

Elastic cartilage

Neuron

Big thing

keratinized stratified squamous epithelium

It has dead looking skin on top
