Study Notes
Skeletal System
- Bones: Frogs have a lightweight, yet strong skeleton made up of 213 bones, which is more than humans (206 bones).
- Vertebral column: Frogs have a unique, flexible vertebral column that allows for jumping and crawling movements.
- Ribs: Frogs have a reduced number of ribs compared to other vertebrates, which helps to reduce weight and increase mobility.
- Limbs: Frogs have four limbs, with the hind legs being larger and more powerful than the forelimbs.
Muscular System
- Muscle types: Frogs have a mix of fast-twitch and slow-twitch muscles, allowing for both rapid, powerful movements and sustained, low-intensity activities.
- Muscle composition: Frog muscles are composed of a high percentage of fast-twitch fibers, which enables rapid contraction and relaxation.
- Muscle function: Frog muscles are designed for explosive jumping and rapid movements, with the hind legs generating most of the power.
Nervous System
- Brain: The frog brain is relatively simple, with a large optic tectum and a well-developed cerebellum.
- Spinal cord: The spinal cord is long and flexible, extending down to the tip of the tail.
- Nerve endings: Frogs have sensitive nerve endings in their skin, which help detect vibrations and movements.
Integumentary System
- Skin: Frog skin is thin, permeable, and highly sensitive, with numerous mucous glands that help to keep the skin moist.
- Mucous glands: These glands produce a protective layer of mucus that helps to prevent water loss and maintain skin hydration.
- Cutaneous respiration: Frogs can absorb oxygen and release carbon dioxide through their skin, which helps to supplement respiratory function.
Respiratory System
- Lungs: Frogs have a pair of lungs that are adapted for gas exchange, but are relatively small compared to the body size.
- Buccal cavity: The buccal cavity, or mouth, is used for gas exchange, with the frog pumping air in and out of the cavity to facilitate respiration.
- Skin respiration: As mentioned earlier, frogs can also absorb oxygen and release carbon dioxide through their skin, which helps to supplement respiratory function.
