SBP Animal Biology

Extracellular Matrix

A component of a certain tissue group that includes protein fibers and ground substances secreted by the cells of this tissue.

Connective Tissues

A diverse group of tissues whose functions include binding, support, protection, cushioning, and fat storage.

Connective Tissue Proper

One of the three main types, which includes loose, dense, reticular, elastic, and adipose tissues.

Loose Connective Tissues

A type of tissue with a watery matrix containing fibroblasts, macrophages, and collagen, elastic, and reticular fibers; found beneath skin epithelia.

Dense Connective Tissues

A type of tissue made of closely packed collagen fiber bundles, found in tendons and ligaments.

Reticular Connective Tissues

A type of tissue made of reticulocytes and reticular fibers that supports soft organs like the spleen and lymph nodes.

Elastic Connective Tissues

A highly flexible tissue containing elastic and collagen fibers, found in large arteries and certain ligaments.

Adipose Tissues

A special type of tissue that stores fats in adipocytes, serving as an energy reservoir and for insulation.

Supportive Connective Tissue

A category that includes cartilage and bone.

Cartilage

A strong, flexible tissue with chondrocytes in a chondrin matrix, found in ears, nose, and joints.

Bones

Hardened tissues with osteocytes and a mineralized matrix, providing the body's structural framework.

Fluid Connective Tissue

A category whose primary example is blood.

Blood

A liquid connective tissue with a plasma matrix and cells like erythrocytes, leukocytes, and thrombocytes.

Skeletal Muscular Tissues

Voluntary, striated muscle tissue attached to bones, responsible for body movement.

Cardiac Muscular Tissues

Involuntary, striated muscle found only in the heart wall, with branching fibers and intercalated discs.

Smooth Muscular Tissues

Involuntary, non-striated muscle tissue found in the walls of hollow organs like the stomach and intestines.

Nervous Tissues

Tissues made up of neurons, found in the brain and spinal cord, specialized for conducting impulses.

Neuron

A nerve cell that typically consists of dendrites, a cell body, and an axon.

Dendrites

The part of a neuron that receives impulses and sends them toward the cell body.

Cell Body

The part of a neuron that contains the nucleus and organelles.

Axon

A long, fiber-like part of a neuron that transmits impulses away from the cell body.
