Brown or brown adipose tissue, characterized by numerous lipid droplets and mitochondria, and high metabolic activity.

A type of adipose tissue, important for heat production (thermogenesis), found primarily in newborns and infants.

A type of adipose tissue containing a large lipid droplet.

Sphere-shaped with elongated cristae in brown adipose tissue; crucial for energy generation and heat production.

Numerous, merging to form a single droplet as the tissue matures, characteristic of brown adipose tissue.

The process of heat production in the body.

Smaller than white adipocytes, about 30-40 micrometers in diameter.

Golden-brown to reddish-brown, due to the high amount of cytochromes.

Predominant fat tissue in adults, stores energy as heat.

Derived from mesenchymal cells

Found in the subcutaneous tissue, perirenal area, and around major organs or vessels.

More prevalent in fetuses/neonates, diminishing in adults in areas including the perirenal, periaortic regions, and ventral neck.

Generates heat as a form of energy.

Supported by connective tissue septa (partitions).

Abundant clumps in the tissue.

Fewer free ribosomes, missing RER.

Adipocytes can be round or polygonal, depending on how many are grouped together.

Adipocytes typically range from 50 to 150 micrometers.

The nucleus of an adipocyte is oval-shaped and located on the edge of the cell.

Adipocytes have few organelles like mitochondria, Golgi apparatus, and some RER.

A single lipid droplet fills most of the adipocyte, not enclosed by a membrane, but by protein filaments.

Adipocyte lipids are replaced every 15-21 days.

Adipocytes are innervated by sympathetic nervous system axons.

Adipocytes have a good blood supply.

Found in the body's many areas, including the mesentery, retroperitoneal space, mammary region, surrounding kidneys, bone marrow, and hypodermis.

Adipocytes with numerous, small, separate lipid droplets inside their cytoplasm.

Adipocytes produce and release adipocytokines into the blood.

Heat production by brown adipose tissue; crucial for maintaining body temperature, especially in newborns.

Creates heat by using mitochondria without producing ATP.

Produce heat rather than ATP in brown adipose tissue, lacking ATP synthase.

A neurotransmitter that stimulates heat production in brown adipose tissue, regulated by the autonomic nervous system.

Newborns heavily depend on brown adipose tissue for heat production, vital for survival.

Dense bone tissue forming the outer layer of bones, characterized by a rigid, organized structure.

Inner bone tissue with a porous, lattice-like structure, composed of trabeculae.

Substance outside bone cells; composed of collagen fibers and mineral salts.

Calcium phosphate crystal, the major mineral component of bone.

Provides support, protection, and a site for calcium storage in the body.

Thin, branching structures of spongy bone.

Bones are categorized as either compact or spongy bone, based on their density and structure.

Maintaining proper calcium levels in the blood by storing/releasing calcium from the bone.

The continuous process of bone tissue destruction and rebuilding in adult bone, involving the replacement of old bone with new bone.

Channels in the bone that contain blood vessels and nerves.

Composed of the brain, spinal cord and nerves; detects & responds to internal/external changes.

The brain and spinal cord, part of the nervous system.

The nerves and ganglia outside the brain and spinal cord; connects CNS to body, nerves.

The basic functional unit of the nervous system; composed of a cell body and extensions for communication.

Controls and coordinates all bodily functions and activities – movement, thought, breathing, heartbeats.

Consists of neurons and supporting cells (glia), along with blood vessels.
