Introduction to Human Anatomy: Lecture 1

Overview

This is our new series on human anatomy and terminology.  It’s been quite a while since we took Dr Mariam Diamond’s class.  Seems like a good time to review.  Today is a 60 minute lecture on anatomy.  Our teacher is white, speaks at a good pace, and seems to be a Jew.

The teacher has a very nice website:

Anatomy  – up, to cut – the study of body structure or morphology.   How the body looks.

Physiology – study of how the body functions, biochemical processes.  How the body works.

This began in 1543 with De Humani Corporis Fabricaf, a 7 volume collection of anatomic drawings.  The author, Andreas Veraluis,  lived from 1514 to 1564.

Levels of Organization – atom, molecule, tissue, tissue system, organ, organism, community, ecosystem, biosphere

From macroscopic to microscopic: gross anatomy, surface, regional, radiological/systemic anatomy, neuroanatomy, histology.

The sternal angle or the angle of Louis.  Take your finger and rub your sternum.  The ridge is the angle of Louis.  Just to the side of that is the second pair of ribs.  That’s the top of the heart.  You must be able to find this on yourself to be able to find this on your patient.

The spinous process of the seventh cervical vertebra.  Cervical means neck.  You can “palpate” or touch/feel it.  A bump on the back of your neck.  It’s an anatomic landmark.  Two spines below the 7th cervical is the top of the heart from the back.

PT vs OT.  PTs or physical therapists focus primarily on the legs.  OT or occupational therapists focuses on the upper extremities.

X rays are used primarily for hard structures like bones and teeth.  Dyes help us see soft tissues.

MRI scans take about 45 minutes a shot.  MRI machines are often in another building or in the basement.

Ultrasound uses high frequency sound.  Is the safest technique, used to see babies.

Major organ systems of the body include the skeletal, circulatory, respiratory, digestive, endocrine, lymphatic, nervous, integumetnary.  There are 9 systems.

Neuroanatomy is available because of its complexity.

There are 60 trillion tissue cells in the human body.  This is studied in cytology.  All living things begin life as a single cell.

Tissue: epithelial, connective, nervous, muscular

Embryology or prenatal development.  Zygote – birth – adult.  Development before birth is prenatal.  After birth its developmental anatomy.  Teratology is the study of birth defects or monsters.

Comparative anatomy compares different animals.  Pathological anatomy covers the anatomy of diseasees.  Patho means disease.

Anatomical position is with the body erect with the arms at the sides.  Palms will be turned forward.  Where is one part of the body releative to another?  This is the reference position

Superior/cranial – toward the hread, the heart is superior to the liver

Inferior/caudal – toward the tail.  The pelvis is inferior to the lungs.

Anterior/ventral – toward the front.  The trachea is anterior to the esophagus.  The trachea is the windpipe.  The esophagus is the foodtube.

Posterior/dorsal – toward the back.  The rectum is posterior to the urinary bladder.

Medial – toward the middle.

Lateral – toward the side.

The stronger the acid, the higher the Ka, the weaker the conjugate base.

AOR = area of responsibility

Catalysts: nickel, platinum, palladium

Markovnikov’s Rule: when an unsymmetrical alkene reacts with a hydrogen halide to give an alkyl halide, the hydrogen adds to the carbon of the alkene that has the greater number of hydrogen substituents, and the halogen to the carbon of the alkene with the fewer number of hydrogen substituents

Response to ambush: Lay down a base of fire, maneuver, indirect-fire support, and close-air support.

“A steady hand, good muscle control, and calm actions may be difficult to achieve when the natural tendency is to panic”

Cheekbone to cheekbone, the widest spot on the head, on an average man was five and three-quarter inches.
