covers passages, lines internal cavities of the body, covers muscles and connects bones

Types of tissue

Epithelial & Connective Tissue

Epithelial Tissue Proper

Sheets of tissue, simple = one layer of cells, Epidermis, mucosal lining-mouth, nose; passages that run outside to inside

Endothelial

Type of epithelial tissue; lines the walls of blood vessels

Mesothelial

Type of epithelial tissue; lines internal body cavities (peritoneal, pleural, pericardial)

Connective Tissue

provides support for your body and connects all its parts

Loose Connective Tissue

netting or mesh, non-solid sheet to allow movement, found under skin (loose with age)
loosely intertwined fibers between cells; types: areolar, adipose, reticular

Dense Connective Tissue

tight dense fibers, strong, does not allow for much movement

2 Types of Dense Connective Tissue

White & Unyielding, Yellow & Elastic

Tendons

attach muscle to muscle, muscle to bone, and muscle to cartilage

Aponeuroses

flat sheets of tendon, connects multiple muscles together

Ligaments

elastic, connecting bone to bone, bone to cartilage or cartilage to cartilage

4 Dense Connective Tissues

Tendons, Ligaments, Fascia, & Reticular Tissue

2 Special Connective Tissue

Cartilage and Bone

Cartilage

described by color, continues to grow

Hyaline

blueish white surface of joint, common in larynx

Elastic Cartilage

(yellow) rubbery--> ear, eustachian tubes

Fibrocartilage

(greyish) in between vertebrae in the back

Bone

dense compact connective tissue, solid osseous bone, covered in periosteum

cancellous

contains red marrow, yellow marrow (edipose contains fat)

Perichondrium

around the cartilage

Long Bone

longer in length than width

Short Bone

more width that length

Flat Bone

skull, sternum, face,etc, thin, flattened, & curved

2 Parts of Skeleton

1) Axial
2)Appendicular

Axial Skeleton

the part of the skeleton that includes the skull and spinal column and sternum and ribs

Appendicular Skeleton

forms the extremeties and is composed of the shoulder girdle, arm bones, pelvic girdle, and leg bones
