1 Hyaline Cartilage Description: Often called gristle, bluish white smokey looking ground substance with a band of numerous chondrocytes. Most abundant type of cartilage in body Location: ends of long bones, ribs, nose, trachea, larynx, & bronchi. Function: For flexibility, support, and smooth surfaces at joints. chondrocytes Ground Substance

2 Elastic Cartilage Description: Chondrocytes are located within threadlike network of elastic fibers. Location: Epiglottis of larynx, external ear, Eustachian tubes Function: For support and shape (ear).

3 Elastic vs Hyaline Cartilage
Lacuna (hollow space holding chondrocyte) chondrocyte Smoother Appearance Of ground substance Elastic fibers throughout Ground substance

4 Fibrocartilage Description: a tough form of cartilage that consists of chondrocytes scattered among clearly visible dense bundles of collagen fibers within the matrix. Location: Intevertebral discs , menisci (cartilage pads) of the knee joint, & pubic symphysis Function: provides support and rigidity ; the strongest of the three types of cartilage.

5 “signet ring” adipocyte
Adipose Tissue Description: Adipocytes, “signet ring” cells with peripheral nuclei. Location: under skin, around heart & kidneys, yellow marrow, behind eyes. Function: For storage of triglycerides, to reduce heat loss, and serve as an energy reserve. nucleus “signet ring” adipocyte

6 Osseous Tissue (Bone) Compact bone consists of osteons (haversion systems) that contain: Lamellae Lacuna Osteocytes Canaliculi Central (haversion) canals Spongy bone consists of thin plates called trabeculae filled with red marrow

7 Lamellae Central(Haversion) Canal Haversion System Lacunae

8 Lacunae (where osteocytes reside)
Canaliculi: small Tunnels where osteocyte processes run for diffusion of nutrients and wastes

9 Skeletal Muscle Tissue
Description: Striated Proteins Actin Myosin Multinucleated Voluntary Location: Attach to bones Function: For movement, communication, posture, heat production Striations

10 Skeletal muscle fiber with multiple nuclei

11

12 Smooth (Visceral) Muscle Tissue
Description: No striations Spindle-shaped Single centrally located nucleus Nucleus is long and cigar shaped Involuntary Location: Viscera Blood vessels Function: Creates walls of hollow structures, aids in movement of internal material.

13 Cigar shaped nuclei

14 Smooth Muscle

15 Cardiac Muscle Tissue Description: Locations: Heart
Striated, mono-nucleated, branching Self excitatory Intercalated discs attach fibers together and contain gap junctions (help with conduction of electrical signals) Locations: Heart Function: Contracts the heart. Intercalated disc nucleus

16 Nervous Tissue (motor neuron)
Description: Cell body: where the cell (neuron) interprets the signal Dendrite: where the signal enter the cell Axon: where the signal exits the cell Glial Cells: forms myelin, and provide support and protection for neurons. Location: Brain, spinal chord, and branching nerves. Function: React to stimuli, carry messages throughout body

17 Name the tissues and structures you see.
