Which 2 spinal curvatures are obvious at birth?
Thoracic & Sacral Curvatures
What bones are connected by the lambdoid suture?
Occipital bone & Parietal bones
What bones are connected by the squamous suture?
Temporal & Parietal bones
What are the 8 bones of the cranium?

2) Right Parietal Bone
3) Left Parietal bone
4) Right Temporal Bone
5) Left Temporal Bone
6) Occipital Bone
7) Sphenoid Bone

What bones contribute to the formation of the orbital fossa?
Frontal Bone
Frontal Process of Maxilla
Orbital Plate of Ethmoid Bone
Orbital Plate of the Maxilla
Lacrimal Bone
Sphenoid Bone
Zygomatic Bone
Which type of bone has the least amount of spongy bone relative to its total volume?
Long Bone
What are examples of Long Bones?
What are examples of short bones?

Examples of irregular bones:
What are the protective functions of the skin?
-insulates & cushions underlying tissues
- desiccation (prevents H2O loss)
- protects from UV radiation
- regulates heat loss
- protects body from damage (mechanical, thermal & bacterial invasion)
4 Basic types of tissues:
1) Epithelial
2) Connective
3) Muscle
4) Neural
Exocrine gland
secretes onto the body surface or into a passageway connected to the exterior
-produce exocrine secretions (perspiration on skin, tears in eyes, milk in mammary glands)
Types of Exocrine Glands:
1) Merocrine Secretion
2) Apocrine Secretion
3) Holocrine Secretion
Merocrine Secretion
released from vesicles via exocytosis
Most common
Ex: mucin=mucous, sweat
Apocrine Secretion
involves loss of cytoplasm + secretory product
Holocrine Secretion
the entire cell becomes packed with secretory products & then bursts, killing the cell
Characteristics of Epithelial Tissues:
cells are tightly joined
bound surface rests on basement membrane
Functions of Epithelial Tissues:
chemoreception forming linings & coverings
Characteristics of connective Tissue:
manufacture & store substances
highly vascular (except cartilage which is avascular)
not found on free surfaces
often named based on fibers produced & concentration of fibers
What are the fibers in CT?
