Miércoles 10 de junio. Sesión 2 de Science. Vídeos, juegos y resumen del tema 1 de Natural Science
Sight 👀:
The Iris control the size and the ammount of the eye.
The optic nerve carried the signals to the brain.
Hearing 👂🏼 :
Auditory
nerve includes innear ear .
Ossicles
includes middle ear .
Eardrum
includes outer ear.
Smell 👃🏼:
Enter in the
nostrils .
Particles
are detected by nerve receptors.
Nerve
receptors send signals to the olfatory bulb
Taste 👅 :
Food touches
the tounge
They have
receptor cells .
Gustatory
nerves carried electrical signals .
Touch 🖐🏼 :
Skin
protects the body
Top layer is
the epidermis and middle layer dermis .
The nerves
send the electrical signals to the brain.
The central nervous system 🧠:
Spinal
cord make up our central nervous
systems.
Brain :
skull protects the brain and has three main parts :
Cerebrum :
is the biggest part of the brain
Cerebellum :
Controls movement, balance and coordination
Brain stem:
Connect the rest of the body to the spinal cord .
Spinal cord : controls our reflex actions such as blinking .
The peripheral nervous system 🧠:
These nerves
are made up of tiny cells called neurons that have dentrites that receive
signals and axons that transmit signals.
1 Sensory
neurons carry signals from the sense organs to the brain .
2 The brain
interprets the information and responds producing signals
3 Motor
neurons carry those signals to the locomotor systems .
The eskeleton🦴:
Short bones: Provides stability and support
Flat bones: Protect our internal organs
Long bones: Are found in legs and arms
Joints:
Fixed joints: Do not move
Semi-fixed joints: Allow some movment
Flexible joints: Allow much more movment
Muscles 🦾:
Skeletal muscles: Are joint to muscles by tendons, are voluntary muscles
Smooth muscles: Are found in organs, are involuntary muscles
Cardiac muscles: Makes the heart move and beat, are involuntary muscles
