Dendrites

Dendrites

________ receive the signals at connections called synapses.

nerve

A(n) ________ is a tissue made up of a bundle of specialized cells called neurons.

Leukocytes

________ are large opaque blood cells that can either engulf (swallow) invading microorganisms or produce antibodies to fight off infection.

smaller branching extensions

What are called dendrites, and this is where the neuron receives signals? Answer with a single words or term.

Lymphocytes

________ are white blood cells that are released in response to foreign invasion, they are designed to identify and mark as "non- self "any foreign cell in the blood, and release antibodies or other forms of defence to destroy the invader.

Plants

________ have cells responsible for growth called meristematic cells, as well as cells responsible for transporting water and sugars.

Unicellular organisms

________ are living creatures made up of only one cell.

Motor neurons

________ carry impulses from the brain to muscles or glands.

presence of a nucleus

The ________ allows white blood cells to alter their function as needed to protect the body from different types of foreign invaders.

Skin

What is the largest organ of the human body, covering its entire surface? Answer with a single words or term.

electrochemical message

If the cell decides to respond, it sends an electrochemical impulse along its axon to the next neuron. This ________ is passed from neuron to neuron at lightning speed.

Bone cells

________ are specialized to give the organism structure and support.

Sperm cells

________ are designed to do one thing- deliver genetic material to an egg as fast as they can.

Skin cells

________ are typically flat and thin with a brick or honeycomb shape that allows them to fit closely together to form a continuous protective layer.

White blood cells

________ are involved in the immune system.

messages

A neuron uses electrochemical messages to communicate with other neurons. These ________ are transmitted by both electrical and chemical processes.

Muscle cells

________ are another type of specialized cell that play an important role in the overall function of animals.

Sensory neurons

________ receive the stimulus and send impulses to the brain.
