Serous membrane
: A thin layer that covers the organs and lines the body cavities.
What are the 4 cavities that make up the thoracic cavity, and what are the 2 cavities that make up the abdominopelvic cavity?
Thoracic:pleural x2, mediastinal , pericardial
Abdominopelvic: abdominal cavity, pelvic cavity
Nucleus
The control center of the cell. Contains the cell DNA and directs cells activities.
Its the boss that holds all the information and gives instruction
Lysosomes
A cells recycling center. Contains enzymes that break down waste materials and cellular debris.They're the cleanup crew that keeps the cell tidy and clean of junk!
The inner and outer layer of the serous membrane is called
: Inner= Visceral layer,
Outer= Parietal layer
Describe the cavities’ relative organization using directional terminology.
1.Pelvic Cavity is Medial to the Abdominal cavity
2.Pleural Cavity is Lateral to Pericardial Cavity
3.Mediastinal is Superior to Pericardial
Smooth endoplasmic reticulum:
produces lipids, detoxifies harmful substances, and stores calcium ions. Its a multitasker in the cell.
Ribosomes
They are the hard working employees at the cells protein factory. They read the instructions from the mRNA and assemble amino acids into proteins. They that make sure protein production runs smoothly.
What typically fills the inside of the cavity:
Serous fluid
Rough endoplasmic reticulum
Its covered in ribosomes, giving it a bumpy appearance. Its responsible for protein synthesis and transportation
Cytoskeleton
The cells internal scaffolding. Provides structure, support, and helps with cell movement. Its's the framework that keeps everything in place and allows the Cell to function properly.
What are the two cavities that make up the posterior/dorsal cavity?
The cranial cavity and the vertebral cavity.
Golgi apparatus
cells postal service, receives, modifies, and packages proteins and lipids for transport to their final destinations. A hub that ensures everything gets sorted and delivered to the right place.
What are the two cavities that make up the anterior/ventral cavity?
The thoracic cavity and the abdominopelvic cavity.
Mitochondria
They produce energy in the form of ATP through cellular respiration. They're like little energy factories that keep the cell running.
