Q

Definition of respiration

A

The exchange of gas between an organism and its environment. This is important for maintaining body systems through an efficient oxygen exchange system of inhalation and exhalation.

Q

What is the spinous process?

A

Extends dorsally and inferiorly from the neural arch. At the midline. This is an attachment point for muscles and ligaments. Spines protect vertebral column.

A

Project laterally on either side of the vertebrae. Project laterally on both sides of the lamina. Attachment point for muscles and ligaments. Ribs articulate with transverse processes and thoracic vertebrae.

21
Q

What is the atlas?

A

The first vertebrae. Supports the way to the skull Very small spinous process. Jellybean sockets articulate with the skull.

22
Q

What is the Axis?

A

Fits into the app list. Allows for rotation and pivoting of the skull.
Dens or odontold process: protrudes through the vertebral foramen. Helps protect damage the spinal cord.

23
Q

What is the transverse ligament?

A

Allows for movement of odontoid process

24
Q

Cervical vertebrae

A

Prominent spinous process. Transverse processes. Enter vertebral framing. Superior and inferior articulate facets . ( allows for rotating and rocking.

25
Q

Thoracic vertebrae

A

12 total, T1 to T 12. Largest spinous and transverse processes than cervical vertebrae. Attachment point for the ribs. Ribs attached to thoracic vertebrae via the superior and in eerier coastal assets. Ribs 1, 10, 11 and 12 have a one-to-one arrangement meaning that Rib 1 attaches to vertebrae one, rib 10 attaches the vertebrate 10 etc. Ribs 2-9 attach to the transverse process as well as attach to the body of the vertebrae above it ( Inferior costal facet).

26
Q

Lumbar vertebrae

A

Five total, L1-L5. Largest and strongest vertebrae because they bear the most weight during lifting or walking. Provided attachment points for back and abdominal muscles.

27
Q

Sacrum

A

Five sacral vertebrae S1-s5. Sacral vertebrae fused together or ossify to form the sacrum. Sacral formina provide passageway for sacral nerves

28
Q

Coccyx

A

4 fused coccygeal vertebrae. Beak-like appearance. Articulates with the sacrum by means of a small disk.

29
Q

What is a normal spine curvature?

A

Straight from anterior to posterior with very slight curve to right. Straight or slightly curves forward in the cervical area, convex in the thoracic region, concave in the lumbar and convex in the sacral area. (It looks like an s with a curved backward at top and a curve forward at the bottom)

30
Q

What is an abnormal curvature of the spine

A

Abnormal: lateral curve. this is also called scoliosis.
Kyphosis or hunchback: abnormal convexity in the thoracic region
Lordosis or swayback: abnormal conductivity in the lumbar or cervical region

31
Q

What is the pelvic girdle, what does it do, and what does it include?

A

The pubic girdle supports lower extremities. Bears the weight for legs. And includes: the Ilium, Ischium, sacrum, pubic bone.

32
Q

Where is the ilium and what does it do?

A

The Iliana is a large wing like bone Support for abdominal muscles. Attachment point for inguinal ligament.

33
Q

Ischium

A

Makes up lower and back portion of hip. Fuses with ilium and pubis.

34
Q

What is the pectoral girdle, what does it do, what does it include?

A

Also known as shoulder girdle. Supports upper extremities. Includes: scapula, clavicle, sternum.

35
Q

Scapula

A

Attachment point for several muscles. Attaches to clavicle.

36
Q

Clavicle

A

Also known as the collarbone. Provides anterior support for shoulder. Attaches to the sternum and anterior portion of scapula.

37
Q

Ribs

A

There 12 pairs.
All attach to sternum by means of costal cartilage except for the lowest two.
Each rib consists of four components: head, neck, shaft, angle
Ribs are classified as true ribs, false ribs, or floating ribs

38
Q

True ribs

A

Consists of upper ribs one through seven.

Direct attachment to the sternum via a cartilaginous union

39
Q

False ribs

A

Ribs eight, nine, and 10.

Attached to the sternum via cartilage which runs superiorly

40
Q

Floating ribs

A

Ribs 11 and 12

Articulate with the vertebral column

41
Q

True or false: all rib attach to the vertebral column

A

True

42
Q

Sternum

A

Has three components: manubrium sterni, Corpus/body, xiphoid (also known as ensiform process)
Attaches to the clavicle
Articulates with ribs by means of costal cartilage

43
Q

Manubrium

A

Uppermost segment of the sternum
Contains jugular notch
Articulates with the clavicle and first rib

44
Q

Body of sternum

A

Articulates with six ribs

Forms the junction of the manubrium and body of the sternum known as the sternal angle

45
Q

Xiphoid process

A

Provides attachment to the linea Alba or midline of the abdomen

46
Q

Respiratory passageway

A

The respiratory passageway provides communication between the lungs and the external environment

Includes:
Oral and nasal cavities
Larynx
Trachea
Bronchi or bronchial tubes
47
Q

Trachea

A

Flexible tube
Approximately 11 cm in length
Composed of 16 to 20 hyaline cartilage rings on the anterior portion of the trachea. These hold the trachea open.
Posterior wall has trachealis muscle to fill the gap between the c-rings

48
Q

How does the air passageways and trachea stay clean?

A

lined with ciliated epithelial mucous membrane

Mucous glands secrete mucus to moisten incoming air and move particles out of the trachea via it’s cilia

49
Q

Where is the trachea located?

A

Runs from inferior border of larynx for approximately 11 cm to a point where it divides into the mainstem bronchi

50
Q

What is the point at which the trachea divides called

A

Carina trachea
