Cardiac Muscle Function

involuntary contraction of heart to pump blood

Cardiac Muscle Structure & Location

striated - heart walls

Collagen Fibers

provides great tensile strength

Elastic Fibers

stretch easily - weaker than collagen

Fibroblasts

produces fibers

Heparin

released by mast cells - prevents blood from clotting

Histamine

released by mast cells - promotes allergic reaction

Ligament

connects bone to bone

Macrophage

act as scavengers carrying out phagocytosis

Mast Cells

secretes heparin and histamine

Nervous Tissue Function

coordinates, regulates, integrates incoming information

Nervous Tissue Location

brain, spinal cord, nerves

Reticular Fibers

lend delicate support to structures

Skeletal Muscle Tissue Function

voluntary movements of skeletal parts

Skeletal Muscle Tissue Structure & Location

striated - attaches to bones

Smooth Muscle Tissue Function

involuntary movements of hollow organs

Smooth Muscle Tissue Structure & Location

lack striations - walls of internal organs

Tendon

connects muscle to bone

Muscle Tissue

major tissue type which is irritable & contracts to provide movement

Adipose Function

protects, insulates, stores fat, available for fuel

Adipose Structure

beneath skin, acts as cushion, insulator

Blood Function

transports material between cells - keeps internal stable environment

Blood Location

throughout body in a closed system of vessels

Bone

hardest connective tissue - supports, protects, framework of skeleton

Dense Connective Tissue Function

strong - withstand pulling - low blood supply

Dense Connective Tissue Location

tendons & ligaments

Elastic Cartilage

provides flexible framework - makes up ear

Fibrocartilage

tough, absorbs shock - in knees & vertebrae

Hyaline Cartilage

abundant, protects, supportive, attachment - ribs & end of bone

Marrow

forms blood cells

Edema

swelling in an area due to excess fluid

Plasma

nonliving fluid that suspends blood cells

Neuron

receive & send electrochemical impulses

Neuroglial Cell

supportive cells to neurons

Peristalsis

wavelike motion - moves food through digestive system
