Q

Explain the epidural space in relation of

A

The spinal cord- pia mater- arachnoid matter- dura matte( more close the vertebral body)- between there is the epidural space( has the epidural fat) - all this enclosed i the vertebral canal

Q

Caudal equina and the difference between spinal cord and spinal nerves was

A

After the spinal cord ends around L1 or L2
Spinal cord is a tube where nerves branchout from. It is part of the CNS
The caudal equina are spinal nerves and spinal rootlets. Part if the peripheral nervous system

Q

The continous process of the dura, arachnoid and pia matter

A

The dura and arachnoid matter will follow the cauda equina into the sacrum
While the pia matter will go down to the coccyx as the filum terminale( an extension of the pia matter) acting as an anchor to the spinal cord

Q

The ventral cavity constituents

A

It consists of the
thoracic cavity
& abdominal cavity
The thoracic cavity includes the plueral cavity, superior and mediasttinum cavity
Abdominal cavity and pelvic cavity

17
Q

Thoracic cavity is made

A

The veryebral body
The rib cages and sternum and costal cartilages

18
Q

What are the Borders of the thoracic cavity

A

Superior
Comprised of the vertebral body,first rib and manubrium of sternum
Lateral
Posterior
Respiratory diaphragm

Posterior anterior laterally
The vertebral bodies
Ribs
Intercostal muscles
Sternum…. Make a bird cage type thing

19
Q

Location of the pleural cavity

A

From outside
Parietal pleura- space( pleural cavity has fluid - viseral pelura

20
Q

Functions of the pleural cavity

A

1 lubrication
2 prevent the lung from collapsing

21
Q

How is does the pleural cavity keep the lung from collapsing

A

Intrapleural pressure is less than intrapulmonary pressure

22
Q

Pericardial cavity
And it’s function

A

It is a fluid located between the parietal pericardium and the visceral pericardium(epicardium)
These two pericardium are found with in the serous membrane

23
Q

The two membranes of the heart

A

1 serous membrane
2 fibrous membrane

24
Q

What are the functions of these two membranes

A

The serous memebrane is used to

The fibrous membrane

25
