What two cavities make up the dorsal body cavity? Catalyst questions What two cavities make up the dorsal body cavity? What organs are contained in each? What organs are in the abdominal cavities? What three cavities branch from the thoracic cavity?

Let’s Review… 1. Cranial cavity and vertebral cavity Cranial contains the cranium and the brain Vertebral contains the vertebral column and the spinal cord 2. digestive organs, spleen, kidney, and ureters 3. The right, left, and medial (mediastinum)

Class update Today is very content heavy, so your test will be NEXT Monday Binder checks will occur at the same time. However, new material will be introduced on Thursday, but not be responsible for it on the test.

Anatomical directions/Body Regions

Today’s objective SWBAT illustrate the directional terms that refer to the body using correct anatomical terminology.

Anatomical Positon Just like we would orient ourselves to refer to N,S,E and W. The is a stance in which a person stands erect with feet flat on the floor, arms at the sides, and the palms, face, and eyes facing forward. This position should be assumed unless stated otherwise,

So much Vocabulary! Let’s make sure we’ve got this

Why is this important? Knowledge of external anatomy, direction, and landmarks of the body is important in performing a physical examination, clinical procedures, and in anatomy class!

For this first time, let’s define them together. Vocab list. For this first time, let’s define them together.

Partner work Have one partner quiz another and the other will have to point to where it is on the body.

Individual work Label parts on the body then add it to EVEN pages in your interactive notebook

Make note cards of the directional/body regions. Study! Homework Make note cards of the directional/body regions. Study! I will be checking the notecards for a grade next class.
