Glossary of Anatomy Lecture Test 1
Other Decks By This User
- Anatomy - gross & microscopic
- Anatomy is the study of body structure
gross anatomy, microscopic anatomy (histology), and developmental anatomy.
the study of body function
- Hierarchy of Structural Organization
- chemical, cellular, tissue, organ, organ system, and the human organism itself.
- organ systems in the body
- integumentary (skin),
circulatory (cardiovascular & immune),
- Organ system
- Organ system – organs working together for a common purpose
Organ level – a discrete structure made up of more than one tissue, most contain all 4 types of tissues
Examples of organs – brain, liver, femur, and duodenum
- The basic structures we share with all other vertebrate animals are the
- tube-within-a-tube body plan, bilateral symmetry, a dorsal hollow nerve cord, notochord and vertebrae, segmentation, and pharyngeal pouches.
- dorsal vs Ventral
- dorsal cavity, subdivided into the cranial and vertebral cavities; and
ventral body cavity, subdivided into the thoracic and abdominopelvic cavites.
- Ventral Cavity contents
- Within the ventral cavity are the visceral organs (heart, lungs, intestines, kidneys, etc.)
three serous cavities: pleural, pericardial, and peritoneal cavities. --cavities are lined by thin membranes, the parietal and visceral serosae (see Figure 1.9). The serosae produce a thin layer of lubricating fluid that decreases friction between moving organs.
- Contents of thorasic cavity
- •Thoracic cavity – divided into three parts
•Two lateral parts each containing a lung surrounded by a pleural cavity
•Mediastinum – contains the heart surrounded by the pericardial sac and other major thoracic organs such as the esophagus & trachea,
- Mediastinum –
contains the heart surrounded by the pericardial sac and other major thoracic organs such as the esophagus & trachea,
- Diaphragm separates the thoracic and abdominopelvic cavities
inserts upon itself
- 38 week prenatal period
- embroytic period
- body plan established
1st 8 weeks of of pre-natal development
est trunk mucscles, vert col, spinal cord, brain, digestive, respiratory tubes, serous cavaties, heart, kidneys, gonads, & limbs
- fertilized egg
- Perichondrium: A dense membrane composed of fibrous connective tissue that closely wraps (invests) all cartilage, except the cartilage in joints which is covered by a synovial membrane. Peri- is a prefix borrowed from the Greek meaning "around or about" and "-chondrium" also comes from a Greek word "chondros" meaning "cartilage or gristle."
- Epidermis layers· From deep to superficial:
"Bad Skin Gets Little Calluses"
- Epidermis layers From superficial to deep:
"Come, Let's Get Sun Burned"
"Can Lori Get Some Gas?"
"Can Larry Get Some Beer?"
- Skull Bones
STEP OFf my skull
"STEP OF 6 "
· The 6 skull bones are:
- Facial Bones
"Virgil Can Not Make My Pet Zebra Laugh!":
- Osteoblast vs. osteoclast
- OsteoBlast Builds bone.
OsteoClast Consumes bone.
- Vertebrae: number of facets
- a typical thoracic has
Typical Thoracic has Ten facets.
- Tibia vs. fibula: which is lateral
- The FibuLA is LAteral.
- vertebral body shape:
- Thoracic is heart-shaped body since your heart is in your thorax.
Lumbar is kidney-bean shaped since kidneys are in lumbar area.
- Elbow joint: radius vs. ulna ends
- CRAzy TULips:
Capitalum = ULnar
Trochlear = RAdius
- Elbow joint: capitulum vs. trochlea
