Anatomy 1 Connective Tissues

Areolar Connective Tissue

A type of loose connective tissue with loosely arranged protein fibers and fibroblasts, found between the skin and deeper tissues.

Fibroblasts

The cells found in both areolar and dense connective tissues responsible for producing fibers.

Dense Regular Connective Tissue

A type of connective tissue with tightly packed, parallel protein fibers, forming tendons and ligaments.

Dense Irregular Connective Tissue

A type of connective tissue with tightly packed fibers arranged in multiple directions, found in the dermis and joint capsules.

Adipose Tissue

A loose connective tissue also known as fat, composed of adipocytes, with functions in energy storage, cushioning, and insulation.

Reticular Connective Tissue

A type of loose connective tissue with reticulocytes and delicate fibers, found in the liver and spleen.

Cartilage

A connective tissue with chondrocytes and a gel-like matrix, providing cushioning and support.

Hyaline Cartilage

A subtype of cartilage with a gel-like matrix and no visible protein fibers, found in joints and fetal skeletons.

Fibrocartilage

A subtype of cartilage with tightly packed protein fibers, forming intervertebral discs and the pubic symphysis.

Elastic Cartilage

A subtype of cartilage with elastic fibers in a gel-like matrix, providing elasticity to structures like the ear.

Bone Tissue

A solid connective tissue with osteocytes, a solid matrix made of calcium, and two types:compact and spongy bone.

Blood

A liquid connective tissue with a liquid matrix, containing red and white blood cells, responsible for transporting substances.

Muscle Tissue

The third major type of tissue responsible for movement, containing contractile proteins.

Skeletal Muscle

A voluntary muscle tissue that moves bones, characterized by cylindrical shape and striations.

Cardiac Muscle

Involuntary muscle tissue forming the heart, with cylindrical and branched cells, striations, and intercalated discs.

Smooth Muscle

Also known as visceral muscle, it is involuntary, spindle-shaped, with one nucleus per cell, and not striated.

Nervous Tissue

The fourth major type of tissue, forming the brain, spinal cord, and nerves, composed of neurons and neuroglial cells.

Neurons

The nerve cells that send nerve impulses.

Neuroglial Cells

Supportive cells in nervous tissue that do not send impulses but care for neurons.
