how can learning to read the bone landmarks be instructive in understanding something about the person from whom the bone came? give three examples from clavicle, scapula, human humerus, radius and ulna, or carpus. Givethe anatomical clues that lead you to these inferences.

Solution

BONE LANDMARKS

Bone osification and its texture and conture helps to identify from which this bone belongs ie male or female.If we talk about superior appendicular skeleton clavicle is of more length as compare to that of female.Mandible is more thicker of male as that of female and ossification is related with sex hormones.

EXAMPLES

CLAVICLE: The clavicle is the only long bone in the body that would be lies horizontally in the human body.

SCAPULA: Scapula is the shoulder bone that connects the humerus.

HUMAN HUMERUS: Is a long bone in the arm or forelimb that runs from the shoulder to the elbow in the human body.

RADIUS AND ULNA: RADIUS Is the one of the two large bones of the forearm in the human body, ULNA is one of the two long bones in the forearm It is on the side opposite the thumb in the human body.

CARPUS: Small bones between the main part of the forelimb and the metacarpus in terrestrial vertebrates.

ANATOMICAL CLUES:

1)-Anatonomy talks about bones, Bones are discrete organs made up of bone tissue, and few other things.

2) Bones consists of both organic and inoragnic matrix and cells.

3) Shape of bones are determined by many factors like genetical,metabolic etc..

4) Metabolic factors are also important: calcium, phosphorous, vitamins A,C and D and the secretions of the pituitary, thyroid, parathyroid adrenals and gonads are all involved in human body.
