What are the basic Types of bones?
long Short flat irregular sesamoid Sutural
What are the characteristics of long bones?
Greater in length than width
Consist of Shaft & extremities (epiphyses)
Mostly Compact bone in diaphysis (shaft)
Spongy bone in epiphyses
Characteristics of short bones?
about equal in length & width
Spongy bone except @ surface; is thin layer of compact bone tissue
Characteristics of flat bones?
Thin
Composed of 2 nearly parallel plates of Compact bone enclosing layer of spongy bones
Provide Protection
These bones are a complex shapes & vary in amount of Spongy & compact bone
Irregular bones
Where do Sesamoid bones develop?
in certain tendons that have considerable friction, tension, & physical stress
What are the characteristics of Sutural bones?
Also called Wormian bones
Classified by location
Small bones located in sutures between cranial bones
Most commonly found in the lamboid suture
What do depressions and openings do in bones?
Participate in joints
Allow passage of soft tissue
What are processes?
Projections/outgrowths
Help form joints
Serve as attachment points for CT
What is Hiltons Law?
Observation that a nerve that innervates a joint also tends to innervate muscle that move the joint, & the skin that covers the attachment of those muscles
Raise as result of embryological development
What is a vascular sinus?
Thin walled vein that has no smooth muscle to alter its diameter
The myotome is?
All muscles or parts of muscles receiving innervation from 1 spinal nerve
A recurrent is?
Running in a reverse direction
