Daily Warm up 10/4 H• Review: • What is the function of stratified columnar? • What is one function of adipose? • Which muscle tissue has many nuclei? • What does the term anatomical position

mean? • There are a lot of components to the human

body: Give an example of how the body is divided?

Daily warm up 10/4 cp• Which type of tissue is involved in sending

signals to all other parts of your body?

• Which type of tissue is involved with external and internal movement?

• Which type of tissue is involved with protecting organs and giving support to the body?

• Which type of tissue has a wide range of functions and one of them is to supply nutrients to epithelial tissues.

Daily Warm up 10/5 H/CP

• STUDY FOR YOUR TISSUES TEST!

• If I hear talking we start- otherwise you have 7 minutes!

Daily Warm up 10/6 H

1. What is the dorsal cavity and ventral cavity?

2. What two terms is this

picture describing?

3. What does distal mean?

Proximal? Give an example of

each word.

4. The thoracic cavity is broken down into three cavities; what are they? And what is in them?

The Human Body: Anatomical Regions, Directions, and Body

Cavities

Overview of Anatomy and Physiology

• AnatomyAnatomy – the structure of body parts

• PhysiologyPhysiology – the function of the body parts

• Don’t forget they go together- form effects function and vice versa.

Homeostasis

• HomeostasisHomeostasis is the ability to maintain a stable internal environment in an ever-changing outside world

Anatomical Position

• Body erect

• Feet slightly apart

• Palms facing forward

• Thumbs point away from body

Anterior and Posterior

view

Anterior and Posterior Positions

• Anterior –

–means towards the front

• Posterior –

–opposite view of anterior; means toward the back

Superior and Inferior

Views

Superior and Inferior ViewsSuperior –

–means the body part is above another part or is closer to the head.

Inferior –

–means the body part is below another part or is closer to the feet

Medial and

Lateral Views

Medial and Lateral Medial -

–Closer to the middle of the body. (Nose is medial to the eyes)

Lateral –

–means toward the side (Ears are lateral to the eyes)

Proximal and Distal

Views

Proximal and Distal Proximal –

– describes a body part that is closer to a point of attachment than another body part. (Elbow is proximal to the wrist) (The point of attachment is shoulder)

Distal –

– opposite of proximal; particular body part is farther from a point of attachment than another body part. (Fingers are distal to the wrist)

Superficial and Deep

Superficial –

–situated near the surface

Deep –

–parts that are more internal

Body Planes Figure 1.8

Body Planes• SagittalSagittal – (cuts) divides the body into right

and left parts

• Midsagittal or medialMidsagittal or medial – sagittal plane that lies on the middle of the body

• FrontalFrontal– divides the body into anterior and posterior parts (front and back)

• Transverse or horizontalTransverse or horizontal– divides the body into superior and inferior parts (top and bottom)

Body Cavities• Dorsal cavityDorsal cavity protects the nervous system,

and is divided into two subdivisions

– Cranial cavity is within the skull and encases the brain

– Vertebral cavity runs within the vertebral column and encases the spinal cord

• Ventral cavityVentral cavity houses the internal organs (viscera), and is divided into three subdivisions: - Thoracic and Abdominal and pelvic cavities

Body Cavities• The abdominopelvic cavity is separated The abdominopelvic cavity is separated

from the superior thoracic cavity by the from the superior thoracic cavity by the dome-shaped diaphragmdome-shaped diaphragm

• It is composed of two subdivisions

– Abdominal cavity – contains the stomach, intestines, spleen, liver, kidney’s gallbladder and other organs

– Pelvic cavity – lies within the pelvis enclosed by hip bones and contains the bladder, reproductive organs, and rectum
