PRAKTIKUM ANATOMI PANCA INDRA SECARA SINGKAT

Summary

The video provides an overview of the human sensory system, focusing on three senses: sight, hearing, and touch. It explains the anatomy of the eye, covering parts like the pupil, iris, lens, and optic nerve. The ear's structure is discussed, highlighting the outer, middle, and inner ear, including components like the cochlea and auditory ossicles. Lastly, the video details skin anatomy, distinguishing between thick and thin skin, and explains various layers and structures like hair follicles, sweat glands, and sensory receptors, such as Meissner's and Pacini corpuscles.

Takeaways

• 👁️ The session focuses on sensory systems, specifically the eye, ear, and skin.
• 👁️ The eye anatomy includes structures like the pupil, iris, cornea, lens, and vitreous humor.
• 👁️ The optic nerve (nervus opticus) is the second cranial nerve and connects to the eye muscles.
• 👁️ The cornea is in contact with contact lenses, and behind it is the aqueous humor.
• 👂 The ear has three parts: outer, middle, and inner ear, with components like the tympanic membrane and cochlea.
• 👂 The ear also includes auditory bones (malleus, incus, stapes) and semicircular canals for balance.
• 🧴 The skin consists of epidermis, dermis, and hypodermis, with varying thickness across body parts.
• 🧴 Thin skin lacks the stratum lucidum layer present in thick skin.
• 🦵 The skin contains hair follicles, sebaceous glands, and muscles like the arrector pili.
• 🤚 Sensory receptors in the skin include Meissner’s corpuscles (touch) and Pacinian corpuscles (pressure).

Q & A

What are the five senses mentioned in the script?

The five senses mentioned are sight (eyes), hearing (ears), smell (nose), touch (skin), and taste (tongue).

Which parts of the eye are described in the manikin?

The parts of the eye described include the pupil, iris, cornea, lens, vitreous body, and optic nerve. It also mentions muscles like the superior and inferior oblique muscles.

What is the function of the pupil in the eye?

The pupil is the opening in the center of the iris that regulates the amount of light entering the eye.

What is the significance of the vitreous body in the eye?

The vitreous body is a gel-like substance in the eye that helps maintain the shape of the eye and supports the retina.

What are the three sections of the ear mentioned in the script?

The three sections of the ear mentioned are the outer ear, middle ear, and inner ear.

What is the function of the tympanic membrane (eardrum)?

The tympanic membrane, or eardrum, vibrates when sound waves hit it, transmitting the sound to the bones of the middle ear.

What role do the semicircular canals play in the ear?

The semicircular canals are responsible for maintaining balance by detecting head movements and orientation.

What are the layers of the skin described in the script?

The layers of the skin described are the epidermis, dermis, and hypodermis. The epidermis includes the stratum corneum, lucidum, granulosum, spinosum, and basale layers.

What is the function of the erector pili muscle in the skin?

The erector pili muscle contracts when a person is frightened, causing the hair to stand on end and creating 'goosebumps.'

What are Meissner and Pacinian corpuscles, and what do they detect?

Meissner corpuscles detect light touch, while Pacinian corpuscles detect pressure and vibrations.
