Bio 201 LAB : Human Anatomy and Physiology.

Anatomy

Is the science that is concerned with body structures and the relationships among them

Physiology

Is the science that is concerned with the functions of the body parts

Chemical

All atoms and molecules in the body

Cellular

All of the cells in the body

Tissue

Groups of cells working together to perform a certain function

Organ

Groups of tissue working together to perform a specific function

System

Several related organs that have a common function

Organism

All body parts functioning together; a single individual

Anatomical Position

The erect position of the body facing forward, feet flat on the floor, arms at the sides, palms face and eyes facing forward

Superior

Toward the head or above other structures

Inferior

Away from the head or below other structures

Anterior

Toward the front or belly surface

Posterior

Toward the back of the body

Medial

Toward the midline

Lateral

Away from the midline

Intermediate

Between two structures

Ipsilateral

On the same side of the body

Contralateral

On the opposite sides of the body

Proximal

Closer to the point of attachment

Distal

Farther from the point of attachment

Superficial (external)

Towards the body's surface

Deep (internal)

Away from the body's surface

Prone

Laying facedown

Supine

Laying faceup

Body Planes

Real or imaginary "slices" of the body used to divide the body for reference

Sagittal Plane

A vertical slice which divides the body into right and left halves

Midsagittal Plane

Passes through the midline, divides body into equal right and left halves

Parasagittal Plane

Doesn't pass through the midline, divides the body into unequal right or left halves

Frontal Plane

Verticle slice that divides the body into anterior and posterior portions

Transverse (Horizontal) Plane

A horizontal slice that divides the body or organ into superior and anterior halves

Oblique Plane

A slice which passes through at an angle

Dorsal Body Cavity

Toward the back of the body. Subdivided into two cavities

Cranial Cavity

Formed by the cranial bones and contains the brain

Vertebral (Spinal) Canal

Formed by the vertebrae and contains the spinal cord

Meninges

Membranes of the dorsal cavity

Ventral Body Cavity

Toward the front of the body, subdivided into two cavities

Thoracic Cavity

The superior cavity that houses the heart and lungs

Pericardial Cavity

A fluid filled space that surrounds the heart

Pleural Cavities

Fluid filled spaces that surrounds each lung

Mediastinum

Central portion of the thoracic cavity

Abdominopelvic Cavity

The inferior portion of the ventral cavity, divided into two cavities

Abdominal Cavity

Contains the stomach, spleen, liver, gallbladder, pancreas, kidneys, and ureters, small intestine, and most of large intestine

Pelvic Cavity

Contains reproductive organs, part of large intestine, urinary bladder, urethra and rectum

Diaphragm

Separates the thoracic and adominopelvic cavities

Serous Membrane

A thin doubled membrane that lines the walls and outer surfaces of the organs of the cavities. Functions to reduce friction by secreting lubricating fluid and to prevent infection from spreading by compartmentalizing organs

Parietal Layer

Refers to part of the membrane that lines the cavity walls

Visceral Layer

Refers to the part of the membrane that lines outer surfaces of the organs within the cavity

Peritoneum

Lines the abdominopelvic cavity and it's organs

Pleura

Adheres to the surface of the lungs and lines the walls of the chest and diagram

Pericardium

Encloses the heart
